If you guys haven't been, you really should hit up MGC in 2016. A bunch of us PCEFXer folks are part of the museum staff, and the show is very much focused on the actual act of...playing video games. If you want to buy collectard shit, there's a sizable vendor space as well, plus arcades and pinballs and whatnot.
Plus there's a dedicated room for Turbo, featuring Joshua and gang. Enough said!
