I'm assuming that when we're talking "meeting" it's not just like, "Oh I saw them at a store once"
I went to the meet and greet thing for Dear Friends and met Nobuo, but I wouldn't really consider that a real meeting.
I've seen celebrities, and I don't really remember which ones because I don't care too much about these things

Ang Lee is married into my extended family, and my coworker is good friends with Josh Dumahel (sp?).
I did have a lunch meeting with Scott Orr (the EA guy who started the NFL Madden series) and his brother, and that was probably the only multimillionaire I've had lunch with. I actually paid for lunch.

So I guess he's "famous" in the video game industry since he's labelled the game making god.
Jam it back in, in the dark.
