I stumbled onto some fan box art for a made up game called Animal Crossing Ice Age which is basically Animal Crossing but it is always winter. I would really love to see this as a fan game. In fact, I tried it myself but since Animal Crossing uses a clock, I couldn't work out a way to program it with my software (Game Maker).
This is another fan box art I stumbled upon for a made up animal crossing game called Animal Crossing Safari Park. It seems to be sort of an exploring game but it seems like it could be made into a fan game. I also tried to make this into a fan game with my software but sort of failed for the same reason.
Anyways, if these were at least fan games, what kind of game could they be? What features would they have?
