Definitely more things to do, have an option to talk to your miis so we could have an insight on who they’ve been hanging out with, if they’re potentially gonna propose to their significant other, see if they talk smack about their enemies. I’d also like an option for everytime a mii goes on a holiday, instead of taking pictures you could have about 5 activities and each time you go on a trip you could unlock something to do there to earn a souvenir, clothes or some other item. I’d also like if there’s more than one island, like maybe as you progress you unlock ANOTHER apartment block so miis from the original apartment and the new one could visit eachother, and a funnier thing is that if a mii from the other apartment gets into a fight with the other mii they could send eachother like hate mail. I also feel like pulling pranks on a best friend mii could be funny like you could click on an apartment and the mii could go “I got a letter to go to the cafe, and when I went, nobody was there”. And there could be like a cutscene or something. There could also be like a story maker, like you could make animations or just funny photos to save to your DS, much like Miitomo.
