Funny, because I'm sick and tired of hearing how wonderful and perfect your power-armored Mary Sues are. Being able to walk for days does not automatically translate into being able to sprint forever. Besides, we're not even talking about real water-guzzling, bench-sitting exhaustion here. We're talking about going from an all-out sprint to a light jog just to take it easy for a bit. How about you go get a stopwatch and take, oh, about four laps around a quarter-mile track where you sprint the straightaways and jog the turns. Then come back and tell me how being able to alternate jogging and sprinting as long as you want is not "superhuman". Of course, the other reason you're not going to get to run like Superman is that Superman is boringly overpowered and un-fun to fight. Kind of like a Space Marine with the wank-o-meter turned all the way up.
That's too bad for you, I'm afraid. Astartes are meant to be overpowered when compared with pretty much anything, that's been a part of 40k canon for decades. Three lungs, one of which is genetically altered to increase capacity and resist toxic gases. Two hearts, one of which is genetically altered to increase efficiency speeding up the blood around the body and allowing them to endure physical duress for much longer than a regular human. Mental "augmentation" (depends on your point of view, could be seen as a negative in certain situations), to make them far more resistant to giving in to physical pain or fatigue. Real humans can only sprint for about 200m and even that I'd reckon 1/6th is probably taking it easy because sprinting is putting your full force into moving as quickly as possible and this is professional athletes we're talking about here, peak physical condition humans. An astarte would most likely stomp the physical conditioning and training of an athlete into the ground not to mention that the food (more like paste when in power-armour.) is created artificially to provide far more energy to the astarte ingesting it meaning their body would be in an even better shape than anything we could possibly hope to achieve in the real world and they do all this while in their power armour. I'd guesstimate that an Astarte can probably sprint somewhere between 800 meters and a kilometer before succumbing to fatigue to the extent of what we see as an athlete but even then, they could perhaps recover from such fatigue at incredible speeds compared to a human athlete. But regardless of all this, for the sake of balance, I see an 8 second sprint as the absolute maximum sprinting time for a balanced third person shooter with a regular "run" and then an optional walk button to increase accuracy and decrease noise made at the cost of being an easier target.
And simply speaking that's still not enough for "sprint forevah". Like I said switching to jogging after a few seconds of sprinting is not a sign of exhaustion, it's just reasonably pacing yourself. The fact that Space Marines in the game will effectively be able to jog indefinitely and that jogging will count as resting for them is already superhuman enough. If you doubt this, like I said go ahead and try out that exercise I mentioned and tell me how restful the jogging sections feel by the second or third lap. A 10-30 second sprint is doable, it's just that the catch is the longer you can sprint the longer it takes to recover. An 8 second sprint is also workable, but by the same token a shorter sprint recovers more quickly. Like I said, being able to "rest" while jogging is ALREADY superhuman. Many people just don't realize that because they see videogame characters do it all the time.
My first point was merely that Marines can and do sprint for ridiculous amounts of time but I see what you're saying. I don't know about the ten to thirty second, I always imagine sprinting in games kind of to be something you do when bogged down by a heavy bolter or something equally as fast firing/heavy hitting, moving from cover to cover at a much faster speed to try and get close to the sod without being torn apart. I generally say 8 because eight seconds is a long time when you actually play the game, it also forces you to have to seek cover in the scenario I mentioned above rather than just zig-zagging all the way across the battlefield. Indeed but other races will be doing so as well (I assume.. wouldn't make much sense not to from a balance standpoint.) and so there is some reason to question what the sprint times and such should be, as I've said previously in this thread I think that Marines should have the longest "overall" sprint simply because they do not move as quickly but have the largest stamina pool with Eldar coming in as the fastest sprinters but with the least pool and Orks coming in somewhere in the middle. I will be disappointed if Orks can't paint their legs red to move fastah.
It just depends on whether you want to have a short sprint that is almost always available (because of the quick recovery), or the potential for a long sprint at the risk of finding yourself out of stamina when you need it most due to its slow recovery. Of course, it is possible that different races could have different styles of sprint. Eldar might be able to make frequent quick dashes allowing them to rapidly flit from cover to cover, while Orks might be able to make long charges to get into melee but then find themselves committed because it'll take their sprint meter a while to recover. For example, in Project Reality you can sprint for about 30-45 seconds if I remember right. The catch is it takes at least 60 seconds to recover, and jumping also takes out a rather large chunk of stamina. So in a typical fight you're pretty much never topped off except for right at the start, and you generally want to try to save some for jumping. Where as a short sprint would be more like your typical CoD sprint. Yeah you can only keep it up for about 8 seconds, but it'll refill in 10 or less so it's basically always up. Though of course, balancing is technically a lot easier if everyone's movement characteristics (walk/run/sprint speeds/durations, jump height, etc.) are the same.
Well that's solved then, ditch the Space Marines as they are the only unbalancing fator in the game, replace them with the Imperial Guard. Issue solved. The must be doing something wrong then or they should have won this ongoing war by now....
One million people versus several quadrillion (if not more). "Quantity has a quality all of its own." And yet that logic can be applied to anything. Nobz are overpowered when compared to a guardsman, obviously Nobz can't be in the game if the guard is making it into the game.
So not the gods that fans make them out to be then? Thank goodness.. Sure it can be, but I don't see 20 threads a day wanting some weird and over powered ability for the Ork faction because there is fictional literature in the Black Library that mentions it. THAT is the problem, not what is and isn't cannon for Space Marines, the problem is that fans of the Space Marines want all of the abilities and powers mentioned in the books for their own personal character in the game, they don't come to play a fair and balanced 40k FPS, they want to be over powered gods killing everything is site and to be honest if they get what they want this game is dead in the water. Lots of people get narky when someone mentions the TT rules, but that fact is that they are balanced, go to the books it's all unbalanced and out of whack, so in all honesty as far as balancing the factions the lore be damned in making a game like this the TT rules are a far superior comparison. Maybe the issue isn't bad writing but bad product management, there is no way that anyone should be getting the lore of the 40k universe from stories, they should be bullet pointed and recorded facts managed solely by Games Workshop and all of the books shouldn't be allowed to deviate from it at all. Look at the unbalanced lore citations, tons of material on LSM, reasonable amounts on Eldar and CSM, next to nothing on Orkz or other adversaries of the Imperium. This is because people write stories for them to be popular, lore should be produced equally in equal amounts for all races in the 40k Universe and it should never rely on literature.
Don't take a few loud people's opinions as every Space Marine fans opinion, I don't want the vast majority of the Space Marine abilities in this game, I just want certain aspects of the game like sprinting, endurance and things similar to that to be as close to fluff as they can be but still in a way that keeps them competitive or rather, balanced because it makes the races feel unique without giving any race a clear advantage in every situation albeit giving them some advantages in some situations. Nowhere in this thread does it say that anyone wants Marines to have a massive advantage when it comes to sprinting or movement in general just that each race plays differently.
