Ahh, the Nintendo Entertainment System (or NES, for short). The console that changed the course of gaming history and brought the US gaming market back from the brink of extinction. It established Nintendo as a household name and introduced players to some of the most iconic franchises and titles the medium has ever seen.
What it also did was have a lot of rare games. Owing to its age and the fact that the landscape of gaming was vastly different back in the 1980s, finding affordable copies of these games is going to be incredibly hard (if you can find the games at all since many have probably been lost to the sands of time). Here are 10 of the rarest and most expensive NES games that might also require your arm and your leg if you want to purchase them.
