A game called Dunk Heroes on NES. It was a basketball game with melee combat involved, and it was awesome fun, and i played it like a hypnotized zombie for hundreds of hours, until i got absurdly good at it. Especially with the Nekketsu and Texas teams, i usually kept a clean sheet at all times

There was a few games before it, but I like to think the first was Age of Empires II. I was an expert player online.

Super Mario World. Still ranks high in my list of greatest games of all time.

Golden Axe on the PC maybe, when I was pretty young. I finished that one so many times. I don't think I used to play it in the highest difficulty though.

I also kick ass in Armored Core. Both in Normal and Next AC's.

Q*bert

Lemmings multiplayer on Amiga 500. That was so good and my friends were so bad at it... in relation to me.

NHL 94 or 95.

 lol NJ5! Golden Axe is one of the easiest games in history. It practically plays by itself.

(funny that u mention this game since u are so knowledgable in this genre, talking about Ninja Gaiden II all the time) ^^

I mastered a few games, but in Mario Kart: Double Dash, no one would play with me.

I got so good I could race and win, while playing with my feet.

Although... I could only do that in 50cc lol. I tried 100cc, but I kept getting 3rd...
