Will there be possible gameplay of Pre-Heresy? like with the primarchs and stuff for the people just starting Warhammer 40k and dont know much about the lore.

I very much doubt it to be honest, It's sort of like an expansion type thing.

That's sad, it was so rich with events and what not but current millenium is good too I suppose. I hope they consider it in the future if they run out of ideas or something.

There was a thread awhile back http://forum.eternalcrusade.com/threads/learning-lore-in-game.153/

In Reference to the thread, Lead Game Designer Brent Ellison said

So there should be some way to learn lore in the game!

Also if you want to learn stuff in the meantime, There is a 40k wiki, Just look about different pages!

sweet, I hope it turns out well.

If the game is successful enough, I wouldn't mind a small expansion over the Unification Wars.

Unification wars or the Battle for Ullanor would be pretty amazing to be a part of. Of course the Primarchs would be very difficult to get right...

Yea im just getting into the Heresy part of Warhammer lore with the Horus Heresy books but there are so many events that went on I dont think they put much in thr books. And I have read the wiki here and there about the events but would be way cooler to play the actual events that happened. And would be awesome if they do something similar to Destiny with planet hopping and exploring, even maybe go into the Warp, but I guess ill have to wait and see. Im jus excited to hear about it cause I've been following this game since last year and found this page today and flipped out.

I would love something like the Codex from Mass Effect. I remember they had something like it in the 40k game Kill Team, but I don't think it was as in depth.

Some kind of single player lore based missions that recreate key moments would be cool. Could offer cosmetic stuff as a reward or something.
