First system I owned was a cheap NES ripoff with those 1000 in 1 games con-job which is actually around 10-1 games only with mutliple hacks, starting point, weapon and lives etc counting as 'new games'.
The first system that I actually requested from my parent specifically was the Mega Drive / Genesis, I wanted it so bad because I lived at a friends place for about a month during school break and he had a Megadrive with Mortal Kombat (blood and all) and Street of Rage 1-3 which we played to death.
The first system that I bought with my own money was Playstation 2, at the time me and my 3 friends all purchase a PS2 for Soul Calibur 2 because we were framerate obsessed freaks that devour the game and went on to lose miserably once we actually met real tourni attending pros.
