PC

I have a bunch of emulators, but I used to play StarCraft often. I have a few games on Steam, I just don't play them often.

Retro

I had a bunch of Nintendo games (SNES, NES and Game Boy) that were fun. We had a computer, so I played a few games on that (it was IBM in 1992) so most of the games I played you had to use your imagination. Plus I used all my lunch money on arcades.
