Super Mario Land 1 on the original GameBoy.
Epicness.

I never did manage to finish that game, though. :p

Need For Speed on the 3DO and NHL 98 on the PS1...I also vaguely remember sometimes playing the original Gameboy

Atari 2600 with games I can't remember and then the NES (or Family Game, like it was called here) with Duck Hunt, Mario and Rad Racer

Sega Master System 2 back in the early 1990s: Alex the kid, Sonic the Hedgehog, Bubble Bobble, Ghouls and ghosts and Wonderboy. 2D games of the 1980s and 1990s provided hours of fun back in their day.
