The Cream of the Crop

Kanno, where is your list!

PS3
1- Disgaea 3
2- Valkyria Chronicles
3- Resistance 2 Online Co-op
And thats it... thank god for PSN and backwards compatability.

360
1 - Borderlands (though not an exclusive) is the only game I've really spent a lot of time on.
2- Last Remnant (its not even that great of a game...)
Just got it recently, so lots of games on the too play list.

DS
1 - Final Fantasy IV
2 - Mega Man ZX / ZXA (both about the same)
3 - Final Fantasy III
4 - Castlevania: Order of Excelsia
5 - Sonic Rush
DS easily has the most titles I like of any current gen console, which is a shame because I feel physicaly the DS is a piece of garbage. (Most of the time I go out and buy a game, come home, DL a ROM and emulate it on my comp.)

PSP
1 - FFT!!!
2 - Jean d'arc
3 - FF Dissidia
4 - Disgaea 1
5 - Disgaea 2
And nothing else...

PS2
1 - DBZ:BT2 (bite me)
2 - Mega Man X Collection (might not count, but I liked it more than anything else on the console.)
3 - Final Fantasy X
4 - Metal Gear Solid 2
5 - Shinning Force EXA
And in conclusion except for the first two I didn't really like any games for the PS2 all that much.

XBOX
1 - Fable
2 - Halo 2
And thats all there is.

GBA
1- Castlevania Aira of Sarrow
2 - Mega Man Z3
3 - Mega Man Z1
4 - Mega Man Z2
5 - Mega Man Z4
Yeah, the GBA didn't offer me much except the MMZ series and one Castlevania game.

PS1
1 - FFT!!!
2 - FFVII
3 - Castlevanis: SotN
4 - Chrono Cross
5 - FFIX
Not as bad as I though, I only had to leave a few titles off.

N64
1 - Zelda: OoT
2 - Smash Bros
3 - Micro machines Racing
I never actually owned a N64, so this isn't a very fair list, but I don't think there would have been very many more.

SNES (oh god why do I have to pick!)
1 - Chrono Tigger
2 - FF6
3 - Mega Man X/2/3 (condensed to save room, and so I don't have to pick)
4 - Super Mario World
5 - Donkey Kong Country
Man that was painfull, I had to leave soooo many games I love off. FF4/5 should probably be in there in places 4&5, but I left them off in favor of more diversity.

Genesis
1- Sonic 2
2 - Sonic 3
3 - Sonic 1
I've never played anything worthwhile other than Sonic on the Genesis, but I also never owned one.

NES
1 - Final Fantasy
2 - Super Mario Bros. 3
3 - Final Fantasy III
4 - Super Mario Bros.
My parents would never get me a NES, so I didn't play too many games for it. I never played the old FFs until ~2004.

EDIT: PC (forgot about that)
1 - FFVII (PC version is superior to PS1 version)
2 - Starcraft
3 - World of Warcraft (hey, a game that has come out in the last decade I like.)
4 - Warcraft 3
I don't really use my PC for playing many games, unless you count emulated games, but that would flood the list with SNES classics :)

And in conclusion the DS, PS1 and SNES are the only consoles I could actually fill up a list easily for, not to mention actually having to make painful cuts. And seeing as the DS titles are all last millennium style games, I can't say the last decade has been kind to me as a gamer.
