Plenty of good games is available...
A few of them:
Doom
Quake I/II
Alien Breed (3D/I/II)
Duke Nuke'em 3D
NAPALM
Dune I/II
Ehm... And loads of others search google for it or try some of the specific amiga-game sites...
I could sit all night mentioning games.. so I think it's best that you explore for your self...
