I play games for entertainment purposes. I played Final Fantasy for the epic CG scenes and diversity (FF3-FF7

). I played Assassins Creed because the storyline intrigued me and how it relates to real history. I spent 1000+ plus hours on Counter-Strike because it's against real players so the outcome is always different and there is actually skill involved rather then mouse-button mashing.
I already knew that D3 wasn't gonna last me that long because after you beat Normal mode, EVERYTHING is pretty much the same... but I can't believe I'm bored of it in a MONTH ...
Nightmare - Rinse, repeat with stronger monsters.
Hell - Rinse, repeat again with even stronger monsters.
Inferno - Rinse, repeat, same monsters but now are so freakin' exponentially overpowered they facesmash you into oblivion then force you to pay 50x repair costs post-patch
Now I just log in for like 20 minutes... try to get some of those Achievements (I'm a bit of a perfectionist) ... then log off to play CS 1.6, NHL12 or something heh...
