Circuits... It's kinda like a pipe connecting game, or is it something else, like the electrolyzer minigame in Ratchet and Clank 2?
As for Picross; I could be mistaken but I think we
might have one on our arcade. We've got a lot of stuff that's cool now, like a couple RPG-like games(Mostly just the turn based battles portion though... But there is a VNOG-styled Action RPG that I kinda like... Even if the scores won't seem to save. =P); I believe there's a strategy game based on StarCraft, though I haven't tested that at all since it runs slowly for me(Take a wild guess why.

); and I'm sure there's other things that'd surprise people.
However; I believe I should try them all first, to make sure they should actually go up. =P
