I don't like games that prioritize the canon guy too much. I especially hate it when the other LIs only get half-baked happy endings, while true happiness is reserved for the canon route (usually the True End). Some games even treat each route as just a reset process for the MC until she reaches the True Ending. I find it so unfair. Why can't every guy have a satisfying, complete happy ending with the MC? Another reason is that I rarely ever fall for the canon guy.
Because of this, I've skipped quite a few popular titles. I know this trope is super common, though, haha...
I really don't like games with this kind of layout:
I play otome games for the characters first (I love looking at the art) and the story comes second. Why on earth would they display the dialogue in a way that covers the entire background and the characters like this? I usually pick games based on the art style first. There have been several games I actually liked (including the one in the picture) but I ended up skipping them anyway just because of this layout.
Also, I can't stand games with tiny text. My eyesight isn't the best, so if a game has poor, small, or hard to read fonts, it's an auto skip for me.
