Terminal Reality put out the call for playtesters to go hands on with Ghostbusters: The Video Game a few weeks ago, giving local folks a chance to play the game months before its release.
If you happen to be in the Dallas/Lewisville, Texas area, you might want to inquire if they're still ongoing. The Craigslist posting notes that there will "several sessions over the next month both during the day and in the evening" so we'd say bug 'em. We've played it, so we'd definitely encourage you to try to do the same. It's not a paying gig, but you do get the bragging rights of having played Ghostbusters.
