Based on a similar thread about minor details that made a game for you, this is about things that aren't part of the main experience, but just bother you every time they come up, whether it's a minor inconvenience or a deal-breaker.
For example, the fact that in Dicey Dungeons, the word "dice" is used as both the plural and singular form, even though the correct singular is "die". And this would be excusable, except that Terry Cavanagh is a native English-speaker. I'm not normally a grammar Nazi, but instances like this in professional products just get on my nerves, to the point where even though I'm really interested in how the game works, I haven't ever played it and I don't plan to until that's fixed.
