Come to think of it, more than any specific developer, the thing I'd miss most from America is indie games, really. I can think of a plenty of Japanese developers and series and even entire genres that I would hate to miss out on, but when I try to enumerate things I would miss from America I come up with Valve and the big amorphous cloud of rainbows and possibilities that is indie games. Probably have to go with GLORIOUS NIPPON on this.
