Tokim, nice to see you!
Maybe it took you so long to receive the authorization because there was a problem with your email account...Sometimes it happens that a message take much time to be delivered.
But now you're here: enjoy your stay
Regarding games, I suggest you to take a look at posts in the gaming forums, so you can have an idea of what people like.
I think the most popular games for PS2 (not counting Sports and Fighting as you said above) are Metal Gear Solid 2, Final Fantasy X, Grand Theft Auto 3 and maybe Silent Hill 2. At least these are the games I see everywhere and they're all damn good games!
