I played this weird interface game a few days ago
https://userinyerface.com/ (play it if you haven't, it's pretty funny) And I thought about doing the same thing with games. That is, do things the "wrong way". I believe it should be a fun exercise in game design, since it forces you to think about what is the right way, and why is it right, what makes the wrong way wrong.
Of course, the lesson at the end of the day is that, unlike interface, there really isn't right and wrong in games or art in general. But it can still be fun. A platformer where the camera stays uncomfortably lagging behind the player and you can't see much further ahead. Then its jump profile is too high and is horizontally slower than normal movement speed.
I want to try that eventually. In the meantime, I'll open this topic for discussion
