The Terminator franchise is one of the most famous movie franchises to ever come out of Hollywood. Terminator II: Judgement Day is still regarded to this day as one of the best sequels ever made. Of course this also spawned several games to me made for different consoles and a pre-production prototype has surfaced on eBay.
A user who goes by rileysentertainment has placed the NES prototype up for sale on eBay and states that it will include both the game and a plastic case. They are currently asking $2,000 for the NES prototype.
