I brought two games to the old Southern Illinois game expo that Rob ran - it was a great experience, and I would do it again if it ever returns. They held up nicely. Lots of help, and lots of eyes on all machines, so I felt very safe and comfortable for my machines.
I keep thinking about bringing a few games to Chicago, but my schedule just won't coincide. Someday, maybe. If I had to choose now, it would be Blackout and BSD. Not museum pieces, but solid players.
Go ahead and bring your machine - its a good experience.
