- Fully 3D and the ability to look up, down, left and right freely without an angle. The rolling-log effect has outstayed its welcome in my opinion.
- Have shops in the town instead of situated far away unlike Main Street (the City is fine as it doesn't have ALL of the shops and the player can choose where the shops are located).
- Expanded City. Have the player become the president and have control of the City and where the buildings are located and what is in the city.
- Each villager will have their own personalities and backstories, as opposed to shared personalities.
- Up to 20 villagers in the town. The City can have random villagers that are or aren't currently in your town and the City should have up to 30 villagers wandering around.
- More cliffs and maybe even a mountain. I was disappointed how New Leaf lacked cliffs (excluding the ones by the beach and to the left or right side of the town where the campsite is). The player should be able to walk up the mountain and get a view of the town from a height.
- Much bigger town. New Leaf's town is tiny compared to the N64 and GCN towns. I find it funny how an N64 game has a much larger map than a 3DS game. Maybe include caves where you can easily find fossils at the risk of causing a cave-in, just like in the movie.
- Redesigned Rosie's eyes from the movie should be used. I don't know why they decided to stick with her old eyes design in City Folk and later.
- More interactions with villagers, such as going for a walk with them if they feel like it and maybe the ability to hug a villager depending on their friendship level with the player.
- The ability to swim without a swimsuit.
- Much larger island. Maybe have more than one island if they want to keep it small.
- References to other Animal Crossing games and the movie.
- Have Tom Nook resume the role of being a store owner again instead of working at Nook's Homes. He's better than the Nooklings in my opinion and he's a very underrated character. Just don't make him sound like a slavedriver (he isn't already one, it's just that people got the impression that he was because in the original game he says that he wanted the player to do the chores that he couldn't get around to doing. He's just lazy, not a slavedriver).
I could go on for longer but THAT is enough for my dream AC game.
ACGC's quality of dialogue and music, ACWW's quality of dialogue, the wifi features and the city of ACCF (yes I actually liked it), ACHHD's villager interactivity, and ACNL's town customization options
