NES/SNES cause of the childhood memories with my parents cause this got me into gaming.
PS1+PS2+N64 were the addition to that.

PS2 was probably the best if you just answer with games and the huge library

PS2>all

1) ps2: I had to travel to Newcastle to get this day one,loved it very much, enough said.
2) Snes: my first console ever gifted to me at the time by my first gf, had so much fun playing all my friends at Mario Kart, street fighter 2 etc such great memories sadly long gone.
3) Mega drive: spent many a day playing Buck Rogers,sonic, pga golf and many others.
4) Xbox 360: my ps3 was gathering dust after first year or two, decided to try Xbox and bought it with Halo 3 and Fallout 3 collector's edition, great fun.

5) ps1 Would have been higher had it not been I had to buy several lol, great games but I had zero luck even my beloved chipped one for imports died on me :(

PSX, PS, PS1, or PSOne. Whatever you want to call it.

As an RPG fan, the PSX is an RPG gold mine with most of the very best games in the genre being on that platform, however it's got a ton of great and very different games from other genres as well. Nightmare Creatures, Twisted Metal 2, Tomb Raider 2, Die Hard Trilogy, Blood Omen, Omega Boost, Ace Combat, Colony Wars, Driver, Need For Speed Hot Pursuit, Crash Bandicoot, King's Field, Armored Core, Symphony of the Night, etc.

   The SNES without doubt for games like  Mario World, Mario RPG, Earthbound, Super Metroid, Chrono Trigger, Final Fantasy VI and so on. The PS2 is a close second place though.
