Endless Paradigm

I have an Original XBOX and have been looking to purchase some more games, here is a list of what I have already:

Midway Arcade Treasures 2

Sega GT 2002 / Jet Set Radio Future

Dead Or Alive

Oddworld Munch's Oddysee

Call Of Duty Finest Hour

Counter-Strike

Half Life 2

Halo Combat & 2

Dance Dance Revolution Ultramix 3

Doom 3

So I have been wanting to buy more games, but I am unsure what to get.
Suggestions would be nice

How about Crimson Skies? Might be a bit niche, played the Windows version though and thought it was p.good.
