It is pretty rare that I find a video game I really enjoy playing, through and through. Usually even just trying to get into actually playing a game is enough to destroy whatever interest I might of had, or any fun I might have derived. Then the controls of the game usually kind of suck for me. Then the gameplay itself is kind of frustrating and not all that much fun.

Minecraft: Terrible menus. Terrible config ui.
Rocket League: Most of the time the ball is off the screen anyway, so how is that supposed to be fun? I literally do not get it.
Anything that falls afoul of parental controls in some horribly bad confusing way: Star Trek Online on Xbox One for example.
Anything with a non FPS 3D camera system, because I have never seen one that doesn't just plain suck, one way or another.
Racing games: I really enjoyed Rally Sport Challenge. Other racing games have been really otherwise meh to me.
Any toys to life games: All of the above problems, plus too expen$ive.
