Haha, well screw me if I knew what game I first played, so I'll interpret the theme as "first, or one of the first games you played and can still remember".
Moon Patrol ftw! Used to watch my big brothers play it when I was 6 and was instantly hooked on throwing coins into noisy machines (but never got into poker machines, oddly enough). It's an absolute classic - set the scene for a gazillion more side-scrolling shooters :up:
Double that, no idea here either. I'm sure it was something on my brother's Amiga 500, but the names are blurry, I can only remember Lemmings. Maybe I stick with the excellent Montgomery Burns...yes..excellent indeed, muahahahahhahahahahahaaaa
Starion. I don't remember much about it and never played it that much, but I remember my dad playing it a lot when I visited. It was like a prequel to Elite.
At the time (1994?) my dad became more addicted than me apparently because when he visited me he wanted to play MegaMaze and when I visited him, MegaMaze was always on.
One day, he did finish level 75 though.. since that day he doesn't even remember anything from it.
Can anyone find an in-game screeny of either Frogger or Advanced Dungeons and Dragons (preferrably the lattter) for the 1982 Mattel IntelliVision? Otherwise I'm going to have to settle for a pic of the cartridge/box.
