To honour the upcoming 30th anniversary of Street Fighter II, Capcom is re-releasing the game on the SNES - and it's only making a small amount of them.
All told, 5,500 cartridges are being made solely for the US market and, according to distributor iam8bit, every single one of them are now sold out. The cartridge itself comes in two versions - 4,500 in "Ryu Headband Red" and 1,000 in "Glow-in-the-Dark Blanka Green". Moreover, those who have managed to secure a copy won't be told what version they're getting, as the selection process is randomised.
Price-wise, each copy is being initially sold for $100 - and that price is probably going to double within a couple of years. Here's the cover and cartridge itself.
