My particularly niche gripe is bad dialogue tree options. There are so many games where the mechanism is selecting an option and watching it play out, but so many of them are shit when it comes to the difference between what you see as the option and what actually is said/done. Heavy Rain did it. ‘What should the character say next? Unreadable zalgotext option A, or unreadable zalgotext option B?’ Or ones where the options on screen are ‘A) I thoroughly agree. B) I thoroughly disagree. or C) What?’ but selecting C means the character isn’t just asking for clarification because ‘What?’ actually points at the voiceline, ‘What the fuck are you talking about, you piece of inhuman filth? I bet your a murdering rapist.’ If I can’t have some idea of what selecting an option will do, I’m not actually playing a game at that point. I might as well be trying to play Mario with a controller that remaps itself randomly.
