Super mario world for the super nintendo and there's also a mario game for the nintendo nes.. but i forgot the name haha.. kirby was also good for nintendo nes
if your talking about the old 3d games this fantasy star online on dreamcast if you mean old as in the systems before the early 3d consoles then super mario world
Call of Duty, the first one. Not particularly old, but considering how fast the FPS industry turns over, likely. There's actually a bit of a challenge in this game; no regenerating health.
old for my age is ps1/N64 (well its what I played when I was little anyway) for ps1 I friggin LOVED the first spyro game and it kept me entertained for days because it wasn't nearly as easy as any of the new ones... for N64 the original super smash bros was pretty fun though there are probably better games I can't really think of them right now
Mario1 and Mario3 where the best on N.E.S Oh also the legend of Zelda on N.E.S Some of the Sonic games on Sega genesis where fun to play And Mega-men on N.E.S
