i also loved Gauntlet and it is funny you would mention Dairy Queen because I played in in a similar place but it was the ghetto version of DQ called Tastee Freez... which I don't think actually exists as a company.

I would consider buying one of these mini machines because the games look simple enough that they would probably hold my interest and could be fun for me and my friends who like video games but don't have the patience to get involved in something that involves 12 buttons to memorize.
