The DC version's save bug is incredibly irritating. I don't know if it happens to everyone, but I've definitely heard other people talking about it. Basically, the further you get into a chapter, the larger save files get - it makes it very difficult to share VMUs with other games because it can get very massive. Sometimes it gets too large to even fit on a VMU all by itself. I think it resets in size at the beginning of a chapter, but it's still not worth dealing with.

If you have to get a console version PS2 would be the pick, but like everyone else is saying the PC version will play the best even on a very modestly-equipped PC.
