I haven't seen anyone else sign up for the meetup yet, but I'm still hopeful that we can get some people together.
I am participating in Ludum Dare this weekend with the Cleveland Game Devs at the Launch House site, and will be trying to generate more interest in the outing. To me, that's just a good way to go about establishing and building a relationship with the park staff, and once they know what we can do, maybe they'll be interested in us helping them out with keeping their antique games in a state of repair.
At this point I have no idea what kind of arrangement they might be open to. Shipping games out might be a little much to ask for, but if they'd allow us to remove cabinets in need of repair to our workshop, I'm sure we could keep them around for a week or two just to test out everything thoroughly to make sure everything is working:) We might need to transport them ourselves, though, who knows.
Anyway, if I can get a few people interested in participating in the outing, that would get us started.
I haven't picked a date yet, but maybe that's holding people back from committing interest. I'll try to look at my calendar and pick a date after this weekend.
