I've played a lot of games the last few days. Among them: Taito's Panic Restaurant (aka Wanpaku Kokkun no Gourmet World in Japan), released for the NES in late 1992.
Anyway, I've been playing the game using an emulator because, well, it's pretty darn expensive. Case in point: One eBay auctioneer is trying to sell a sealed copy of it for $3,599.99. (Another is selling a similarly pristine copy of the game for just $1,799.99.)
Opened copies of the game are cheaper, of course, although I'd hardly call them cheap. Loose copies, for instance, commonly command prices above $100.
