That makes sense. It was just an idea I had while texting a buddy about playing some 7dtd tonight. I don't know much about the game engine they used to create the game. All I know is that most games take a fair amount of optimization to run smoothly on consoles.
I have enjoyed the game this long with the limited things to do on console. I would even be more than happy to purchase the game again once its finished and found a publisher to port and distribute it to next gen consoles.
