PAIN is one of those games you play for maybe 20 minutes and move to something else. Gets stale quickly.
Graphically the game is nice, the cartoon-ish feel always makes me laugh when I play. Not much else to say really, not terrible, but not something that will blow you away either.
The big problem I had with this game was the fact it feels VERY slow, and no matter what you do, after launch, I feel useless (even with the OOCH, etc. controls) Launch, watch, relaunch, watch, launch...you get the idea.
Like I said in the beginning, PAIN is one of those games that you play when you need a break from your other games, or just need a cheap laugh.
'Wow, I my fingers hurt from Guitar Hero. I guess I'll play a little PAIN'
While I find myself coming back for more, it's more of a guilty pleasure than an entertaining game.
In conclusion, PAIN feels very shallow, repetitive, and bland. If you're a trophy hunter, don't bother. While yes, there are trophies, they are very hard to obtain, and you won't feel very accomplished when you get them.
