What should I buy?

Also, Ratchet and Clank 2 comes out soon.

And, if you loved FF Tactics, I'd recommend Disgaea: Hour of Darkness. It's a strangely humorous strategy RPG from the guys who made Ogre Battle.

Dynasty Warriors 4 kicks ass

I think Castlevania Lament of Innocence is fun.I reccomend it for everyone who likes RPGs Castlevania or both.

Jak 2 has got to be the best platform game I've ever played on a 32 bit console. It's a nice challenge for once.

PS2 is 128-bit...

Rent all of the games suggested before you buy:
Metal Gear Solid 2: Substance (if you don't already have it on Xbox)
Rent: Way of the Samurai: it's really short and fairly easy but fun fun fun.
Virtua Fighter 4: if you like fighters
LOTR: Two Towers: a good solid hack n' slash
Tenchu 3 is an excellent ninja game.
Rent: Onimusha and Onimusha 2: short but very sweet.
And of course, GTA3 and VC if you aren't planning on getting the cheaper two-in-one pack for Xbox

Any of these are good for starters, after that you know what you like.

Which is also on PS2 now.

i would buy ffx-2 that game are going to be one of the hot game odf this year i say.

hmm i also recomend DW4 it is quite the awsome game, but i enjoyed red faction one more that 2 mainly cause u can blow Every thing up hehe i used to make tunnels form one end of the stage to the other in multiplayer mode, and u could just dig into the side of a wall then make a hole under u then just stand it it and shoot the poor bots hehe

A game I like that I got to play a little is karaoke revolution.Even though I have an extremely deep voice that makes it impossible to sing songs that are high-pitched I still like it.It has some pretty fun songs to sing like addicted,celebration and crawling in the dark.As long as you are a decent singer you will love this game.

Need for speed is a cool game.. midnight run 2 is ok too

you should defenitely get castlevania lament of innocence.That is a pretty fun game.
