Look for bargain bin games, those are usually really small. The GTA double pack is rather small (separately). Off the top of my head some small games Cel Damage, Doom 3: Resurrection of Evil (fits on CDR once you rip the movies),GTA3, GTA:VC, NightCaster,Tony Hawk 2x, Combat: Road to Berlin, Ford Street Racing, Combat: Task Force 121, Samurai Shodown V, SNK vs. Capcom 2, Ford Racing 3, Motocross Mania, Splat! Renegade Paintball, Gotcha!, Kill.Switch, House of the Dead 3, Serious Sam.....lots lots lots.
