I'd go SNES.

It wasn't lacking any one genre... and to me the SNES RPGS have never been matched... or even close to be matched.

The top 3 RPGs in my mind are Final Fantasy 6, Chrono Trigger and Earhtbound. Not to mention all the other really good RPGs that were out on that system.

n64

My best experiances a with a console are as follows.

1.) GameCube (Mainly thanks to multiplayer Melee, played with friends all the time; Also first Zelda Experiance)
2.) Wii (Is second untill I get smash which will counteract melee; Also first Metroid Experiance)
3.) N64 (The first console I played with friends, but not alot. Missing out on Zelda Downgraded it.)

For me, It wasn't just the games, it was the multiplayer abilities. The better the multiplayer experiance on a console, the more fun it is.

3. Neo-Geo, the real hardcore gamer's console

PS2

Wii

I can play all my favorite nes/snes/n64 games (eventually at least, and maybe not including goldeneye) + gc games + wii games and motion controls >>>>>>>>>>>> gamepad


if i had to pick an older system, it'd prolly be NES because I grew up playing those games with friends...SNES/Genesis were great and then N64 wowed me with SM64/Waverace and then MarioKart/Goldeneye = 3434324324 hours with friends...ps1 had Rayman, Castlevania:SotN and Ridge Racer; ps2/gc were fun, but no game on those systems WOWed me like zelda/smb1 did when i was young, sonic did on genesis and then sm64/waverace did on n64

(btw, shouldn't this be in the GAMING forum instead of the NINTENDO forum?)

SNES ... totally

PS2 - The most games across the most genres by far. Action, adventure, platformers, racing sims, offstyle racers, shooters, shmups, etc.

PS1 - Same as above, and really expanded the industry at a time that it probably would have stagnated had it been left to Sega and Nintendo.

SNES/Genesis - Both had a great catalog of games and strong franchises and between the two of them covered everything.
