Don't forget the psx ones.
Point blank 1, 2 & 3
Time crisis 1 and time crisis project titan
Gunfighter 1 legend of jesse james
crypt killer
Lethal enforcers 1 & 2 (one disc)
area 51 (psx)
ghoul panic (pal/uk)
Plus I think "loaded" and "reloaded"

and not sure if anybody mentioned ninja assault for ps2.

With all these psx and ps2 you should have plenty to blast away at.
I gotta admit it. I love my gun games.
