I was watching this tonight and couldn't help but think of how much better Star Citizen would have been if they stuck with Crytek and Cry engine instead of going to Amazon's fork of it with lumberyard and then star engine .
From what I understand RSI forked off CryEngine a long time before they officially moved to Lumberyard (which was really only a branding exercise). I also think they did a "hard" fork instead of keeping a patch set from the fork event.
