Just as the title says...What game got you started. This assumes you play a little more then the average person does. It means you're a "true" gamer in the sence of all the time and devotion you put into your gaming. So lets hear what got you guys started. Your "entry game" ;)
For me it was Wolfenstein 3D.
I remember making maps for it with WolfEdit way back when. Ya sure I had the original Nintendo unit with Mario/duckhunt, but when I played that it was more of a liesure thing.
