What does the cab itself look like? It's hard to say until one sees how the whole thing is put together.
I don't know if I would include more than one character from any one specific game. A little unfair to give PacMan characters two spots and Q-bert gets only one.
I'm a huge huge fan of Stargate. I have to get my SG fix, no matter where it comes from. SGA, SG-1, SG:U, I don't give a flip, just feed it to me.
Pissed me off that they killed SG-1 and SGA, guess I'll have to be happy with SG:U until the whole series becomes another X-Files or Xena.
