What game was it that you picked up and said, "this trout is awesome, where can I find more of this"? What game started it all for you?

Tomb Raider is the first game I ever played that made me really like gaming and want to look for other games that I might be interested in. I think I picked it up for the first time when I was eight or nine and thought, "this trout is amazing, I never want it to end." I hardly consider myself a gamer - rather, I just kinda play games when I feel like it, but Tomb Raider was the first one that did it for me.

So, what is it, folks? Space Invaders? Mario Bros.? Spyro the Dragon? Pong?
