this was one guys idea, and he alone built the framework it seems. but after that initial part was done it was too much and he enlisted the help of fellow players. and it looks like they did a great job. cool stuff.
I bought the pc version about a month ago. I played a good amount of a pirated version awhile back, and the success of the 360 version got me kinda curious again. I've put maybe 3-4 hours into it since then, maybe not the best purchase but whatever.
