Nes - Super Mario Bros. of course!

Sega Genesis - Favourite game is hard to judge, it was either Streets of Rage, James Pond II, or Boxing. Wait, I really liked NHL 94 too.

Nintendo 64 when I was 4 years old. Which was 8 years ago.

Favorite game was Super Mario 64.

First console; Amiga 500, favourite games were Buggy Boy and Super Frog. The first conventional (at least the way we way consoles now) was the NES back in christmas of 89 and the favourite game was Ski or Die, but the Turtles games later became big favourites!
Ahh, those were the days!

My first console was the Philips Videopac (also known as Magnavox Odyssey² in North America).

My first game on it was probably 1. Race / Spin Out / Cryptogram and my favorite was 43. Pickaxe Pete (my current avatar).

As for handhelds, I had 3 Game&Watch games (one got lost) and my favorite was Donkey Kong II.

Nintendo 64: Super Mario 64

I had an atari 2600 that didn't work after a week (probably cuz i didn't know how to work the AV switch on the back of the TV cuz i found it later in my garage and it worked fine) but that system only had a two player baseball game (Only child).

So my first true ownership of a game system was the Sega Genesis with Sonic 2 as a pack in (Best deal ever). Sonic 2 is still my fav game ever so that would be my pick.

1st played was TRS-80, some text adventures
1st with graphics was C-64, game: Where in the World is Carmen Sandiego?
1st owned was Atari 2600, fave game was Adventure

PS1 Gran Turismo

The Sega Genesis. Favourite game was: Sonic 3 and Knuckles.
Fun Fact: Did you know my first word was Sega?
