In all seriousness, I have fond memories of Prince Clumsy and Fox Fights Back on the Commodore 64 but I'm not sure if they were commercial success' or not.

Demon's Crest, Final Fight 3, Golden Axe 3, Denjin Makai II, Bahamut Lagoon, Battle Circuit, The Last Blade 1&2, Tyrian, God Hand, Atelier Iris 3, Batsugun, ESP Ra.De., Sin & Punishment 2...

Ghost Trick: Phantom Detective

It was overshadowed by the Genesis version. Only Sonic 1 made it on the Master System in North America.

Really fun shoot 'em up. It got a port on the PSP later on.

Twin Peaks: The game.

I might be mistaken but aren't the GameGear Sonics essentially the Master System ones?

Ah okay! It looks like Sonic 2 on GG is pretty similar to the Master System version except with a lower resolution and a few graphic changes. I own the GG version but sadly the battery part of my GameGear is fried . I could get another one or buy the Master System version on the VC.

Does Resistance 3 count? That game was amazing.

Dunno if all of these count (and super not in the mood to look up numbers), but these are all the games I remember over the years having to introduce / explain to friends.

Folklore, Sin & Punishment 2, A Boy and His Blob (Wii), Batman Brave and the Bold (Wii), Gunstar Heroes, Earthbound, Lufia 2, Suikoden 2, Devil Dice, Rocket Knight Adventures 1 & 2, Wild Arms 2

Edit: Oh yeah, Arc Rise Fantasia, one of the best jrpgs of last gen that nobody seems to have played. Endearingly bad voice acting, a plot that twists harder than anyone should expect, and a battle system reminiscent of FF10 but different enough to stand on its own.

have you played gunstar super heroes on the gba? it's a sort-of-sequel/reimagining... sold awfully, but brilliant stuff:
