Isn't it weird to think, Nintendo used to be open to porting their games to other systems? When you zoom out and think about it, I guess, in a way, it's even weirder how some games are tied to a certain system, especially given how the industry is moving toward ditching physical games... I mean, imagine if a CD or a movie, was tied to a certain player. That would be so weird. In a sense, what Nintendo did back then, actually did make a lot of sense - at least from a consumer perspective... but as a business? A lot more money to be made, by making exclusive games. PLEASE NOTE: All of our Colecovision games are untested , as we don't have the equipment to do so - but that's why you get a 2-year warranty! Condition: Good.
