I could probably think up more systems, but those are my "Top 3" systems or whatever, I love each one the same.

And finally, Arcade. Even though I've been into emulation almost since it really got started, I've always been kind of stuck in what games I like as far as arcade emulation. CPS1, CPS2, classics. So this one will probably be pretty typical. And bear in mind, I'm going off the top of my head for this one.
