What I often find myself wondering is why people dislike the Super Mario Galaxy games. It's really interesting that I'm so in love with them now, because I originally thought the designers went in completely the wrong direction and never really wanted to have anything to do with the first one...
Nonexistent/inadequate tutorials, especially when controls are complex.
Cutscenes you can't skip.
Games in which you can't replay missions or levels.
Games that overwrite your progress and send you back to the beginning/allow you to do nothing but replay the last level after beating them.
Games...
