I've been playing games as long as I remember. Started, as I recall, with solitaire on an old DOS computer, or possibly these old minigames that came on 5 1/4" floppies (Digdug, Bananoid, Spinwall, and others I've forgotten).
First "traditional" game I remember playing was probably Hillsfar (DOS computer), though I did look over my dad's shoulder earlier than that, while he played Pool of Radiance.
