games advice

I'm a PS2 owner who has just jumped ship and bought an Xbox...I figured that since the system and games are now so cheap why not give it a try. I already have 85 games for PS2 including Res Evil, Grand Theft, Prince of Persia, God of War etc...but need advice on games for the Xbox.

I bought Halo, Fable, Tetris Worlds/Star Wars; Clone Wars and Shrek; Super Party (I have neices to entertain).

I'm going to get Ninja Gaiden Black, Halo 2, Halflife 2, Doom 3, Far Cry Instincts, Oddworld, Chronicles of Riddick and Theif; Deadly Shadows

Any advice on what else to get? or should I rethink any of the games above?

Ninja Gaiden Black, Halo 2, Doom 3. Since you already mentioned you are going to get those games, get Dead or Alive Ultimate. Quite possibly one of the greatest games of all time.

Jet Set Radio Future (really weird, but really good)

Freedom Fighters (if you dont have it on the PS2 yet)

Star Wars: Knights of the Old Republic (best rpg on Xbox)

Rallisport Challenge 2 (best driving game on Xbox)

Panzer Dragoon Orta (definitive "railed shooter")

Fable: The Lost Chapters (short, but really good)

Breakdown (first person brawler thing.  Another weird but good)

For FPS games I recommend:
     Black
     Rainbow Six 3: Black Arrow
     Ghost Recon 2: Summit Strike
     Project Snowblind
     Time Splitters: Future Perfect

For TPS games I recommend:
     Hitman Blood Money
     Freedom Fighters
     Psi Ops

For RPG games I recommend:
     X-Men Legends 2
     Fable Lost Chapters

Kingdom Under Fire Heroes .

Good game.
