Hm. Do we real have to clone a game? Or can we make something, which has a retro-look, might has some gameplay elemts and the controls of a retro game, but which isn't a direct clone of a game?
No, you don't have to clone a game - just make sure that your demo has that hard to describe retro feel Joozey, I look forward to seeing your LBA remake - that was a great game (and I'd say quite advanced for its era).
i'll join for first time to the contest with a remake of Tunnels of Armageddon. It was the only game into my fathers' mmx286 for a long time. It'll be fun.
