Has anyone here tried Miitomo? It's an app for mobile phones made by Nintendo that uses the funny little Mii characters. All you do is answer silly questions, look at your friend's answers, buy crazy outfits, and make hilarious photos. The game does have microtransactions but they are very hidden. They don't pop up and hassle you all the time but they are there. They just keep them back in the menus which is good.
The game is free, of course, but it's a fun time waster. It's a lot more fun when you can get a lot of friends on there and start doing weird stuff. You can customize different parts of your voice and even swear!
Check out this picture I made if you need some persuasion.
