Big world, kinda like club penguin, maybe with periodic puzzle dungeons appearing in the world that you can check out with friends, and get new forms from. Customize your wizard (hat, nose, ears, glasses/eyes, shoes, wand, etc.) and go hang out/chat with your friends! I don’t think I’d want, like, a big digital economy or anything, but maybe you can teach other players spells/forms if they want them. And then maybe some minigames along with the puzzles, just as something else to do
Do I know enough about netcode/server hosting to do this? Probably not. Can I still dream about it? Yes I can
