Yes, I know this process very well. It's called 'white knight awakening'. No offence, I went through it myself and feel exactly like you now, maybe a bit more to the 'dark side' but this is exactly it. It's funny to observe the forums and notice the guys who were once the most loyal EC supporters turn to ...hmmm what should I say? - complete burn outs. This is what BHVR managed to achieve at the level of perfection - turn the most loyal fan base one could dream of away. Well done.
It's more fun to just sit back and watch, anyways. You got the diehard fans who firmly believe that this game will become what it should be, holding up plaques of what the devs promised and shouting into the distance with cotton stuffed in their ears. Then on the other end of the spectrum you have those creepy old guys up on crates, holding up picket signs and claiming that the game is shit and always will be, calling anyone who doesn't share their view an unenlightened fool. Just log on every now and again, mow down some heretics, then come back some other time. The game's not going anywhere anytime soon, and neither are the naysayers or... yaysayers?
At least other shooters are fun til a certain amount of time, which is usually the gaming burnout threshold. But this game...it is frustrating as hell to play. I don't believe that there is even a burn out threshold for this game, it's more like a limit to the amount of frustration and repetitive boredom a normal human being could handle from playing this alpha release of a game.
