Do you not mind
? Then the Saturn library is pretty decent.
Panzer Dragoon and
Panzer Dragoon Zwei for rail shooters;
Virtua Cop,
Virtua Cop 2 and
House of the Dead for light gun shooters;
Radiant Silvergun,
Battle Garegga,
Sokyougurentai,
Dodonpachi,
Hyperduel,
Tempest 2000 for shmups; several
Street Fighter/
vs. Street Fighter,
King of Fighters and
Virtua Fighter games for fighting games (as well as several one-off fighters - the console's bread and butter is shmups and fighting games, really);
Guardian Heroes,
Astal for brawlers;
Shining the Holy Ark,
Shining Force III,
Dragon Force,
Magic Knight Rayearth,
Panzer Dragoon Saga for RPGs;
Powerslave and surprisingly good ports of

Mega Man 8,
Mega Man X4, a frankly-superior version of
Sonic 3D Blast,
Sonic Jam,
Tomb Raider, the
Clockwork Knight series (well,
I like them :<) for platformers; esoteric titles like
NiGHTs,
Burning Rangers...
