Topic: Have you ever played a game that changed your life somewhat?

Well, Spyro the dragon was the first game I ever played.
Scribblenauts introduced me to this site.

Mega Man 2 and Ocarina of Time.

In Ocarina of Time when I ventured into Hyrule Field, the amazing music, the bright big landscape. It changed how I viewed the entire genre of both fantasy and video games. (I didn't know much about Zelda, I had played a bit of Link to the Past and that's it)
So... yeah.
Oh yeah, and Mario & Luigi: Superstar Saga, for being my first RPG and a dang good one. And Paper Mario for preceding it and being just as awesome, if not more. Because it's pretty much the same.
'Cause they're awesome.

lol

I'd say Conker's Bad Fur Day, because it showed me just how funny a game could be without sacrificing fun. It also taught me that boobs are awesome.

And Sonic Adventure 2, because it showed me how much freaking work pets are.

Oh, and Bubble Bobble, for being the first game I played, and making me love video games.

Tales of Monkey Island: Chapter 4: The Trial And Execution of Guybrush Threepwood because it taught me that videogames can be dramatic like a movie.

(hi-fives Shadx)

SM64, OoT, SF64, MK64, made me love games.
Luigi's Mansion _{and to a lesser extent, MP5} the first games I owned, along with a GC.
Water Warfare, why I joined this site
