Nintendo 64 even though I've had a lot more games for the more recent systems and even for systems before it (I think) I had a lot of fun with it and replayed the same few games to death. I think it had to do with my age, playing my first 3d games on a console and having more freedom of movement and action than former generations.
I can still play Mario 64 and Mario Kart 64 to this day and not get bored of them. Goldeneye hasn't aged as gracefully but I put in a lot of hours back in the day, can't play it any more though. I never owned a Playstation and Sega Saturn while I had the N64.
I also still own it back home while on the other hand, I didn't hold on to the Sega Master System, Gameboy, Mega Drive, Game Gear, PS2, PSP, DS or Wii after I moved on. If the next Xbox and PS are backwards compatible won't hold on to the current systems either.
