Holy shit..... guys........ I dont think I beat any games when I was wee laddie... My dad always beat Tetris, got far in Mario.... Games used to scare me...... Even though now my friends call me the master of Nintendo and stuff..... hmmmmmm.... never owned a Super NES untill about 3 years ago.... got a nes when I was 3..... Got a GB when I was 5..... got a 64 when I was 7..... Never beat, Mario 2, Beat Mario and Mario 3 when I was in grade 9.... I was scared of the 3rd Bowser in Mario 64 for a long time.... Scared of Volvaga and the Wall Masters and stuff..... arg....... I would be guessing it would be a GB game.......... This is sad.... my life is meaningless now......
Alien Storm for the Sega Mega Drive followed by Streets of Rage.
I of course can't count the Atari 2600 I played before that cos....wasn't a big fan of it....didn't enjoy it. Plus there wasn't really a plot to those games. Which meant that they looped i.e had no ending so to say.
I don't remember the first game I beat. However, I do remember the game I beat the fastest: Rygar for the NES. Rented it, played it, beat in in about an hour and a half, returned it to the store and rented another game.
I think it was probably Super Mario 64... Either that, or Banjo-Kazooie! For some reason I'm leaning more towards Banjo-Kazooie, and might've gotten all the stars in Mario after that...
