Do you remember the first video game you ever beat all the way through?

Mine was Teenage Mutant Ninja Turtles IV: Turtles in Time on SNES. I was probably 8 or 9 when I beat it for the first time. I was so proud of myself. One thing that sucks about the game is you can't save. You have the play the whole game in one sitting. At the time I was really good at playing the first few stages but I had only seen the last couple of stages just a handful of times. When I finally beat Super Shedder at the end I remember jumping around screaming "yes".

I still have the game and I still love it.
