Wii series.
Its a bunch of mini games with no depth. Everytime you play the games you start to like them just to get disappointed by lack of modes/options/ideas/levels/etc.
All of them are prototypes with extremely functional visuals that dont appeal to most people at all. Its not that they lack visual punch (which they obviously do) its the slack of any kind of good art-style. The Miis look like shit (tomodachi litfe is the first game where they look good! But I somewhat dont count this as mii game for whatever reason)
Its like they want to test how something might work as a game then they make a simple prototype with extremely cheap visuals and then drop the whole thing.
A friend of mine played Wii Fit U for the first time and wondered why is there just 1 stage to run / twhy cant he chance difficulties or speed in all "modes" and is Wii Fit U singleplayer (treaining with friends online would be cool like jogging against other people not just with a dog and some random NPCs walking around etc)
All Mii games have alot of potential but they are just way to limited in what they offer. (Mario&Sonic at Socchi also has this problem alot of nice modes but all modes are wasted because they lack actual content)
