The first one was a contest entry using the Unreal Tournament Engine. Those same guys are now getting paid lots of $$$ to make RO 2, and it looks amazing at first glance so far! Its going to have a much more in depth class system and leveling (not sure if I like this, I prefer the limited number of each class allowed currently....no 10 man sniper teams or anything). Will be interesting to watch and I hope it lives up to my expectations.
