I've been looking into some RPG games to spend my time on and I mainly have my eye on these three:
Diablo III
Mass Effect 2
KotOR II (Star Wars: Knights of the Old Republic)
Obviously as Diablo III isn't out yet this is more of a speculative question on how important it was for the second installment and whether or not that will likely carry over to the third.
Anyways, my question is for anyone who has experience with any of these series(if you don't have experience with all, please say which you do in your post), how important was it to play the first installment before the second? Was it really significant in understanding and enjoying the game or would I be better off not spending my money on the first and just buying the second?
Edit: And one other question.. how long did/have you played these games? My main issue with buying console games is that I hate spending money on one only to beat it in a couple weeks then never play it again, so I'm hoping these aren't similar.
Also.. I'd be playing these on my computer.
