It's a really good game but it's pretty short-it only takes about a week to beat. Also the graphics are excellent for a PSP game. I don't see why a lot of pro reviewers critized the camera. I think it's as good as the PSP can get. Bottom line: Not as good as the first 4 but still a good game.
On the multiplayer version, there is chat. But there are no freakin' filters!!!!!!!!!!!! I once heard someone say all the cuss words ever known in one message, but there are filters for ;(%$ and etc. Plus, people can murder each other even on chat. I suggest that you don't let kids 10 or younger play the multiplayer version.
It's not too violent: no blood and gore involved only energy blasts and electricity shocks
its a good way to start to play adventure and action games before becoming 12+ when there are other, more violent, games.
I bought this game when i was 8 years old and i didn't start grabbing stuff and hitting people XD!
