Mine would be arbitrarily slowing down a character to maintain horror in a game. I get if there are reasons like age, injury, or location that could provide context, but don’t turn my legs into molasses because you need to time the jump scare just right.
Mobile games that have waiting as a mechanic. Like you can only do so much, then you need to either stop or pay. I realise this is a much hated genre already.
Back when Clash of Clans was big, I’d have students sleep through the entire day. I’d call the mum, “please take all phones and computers from your child’s room after 8pm”. After that the kids would absolutely hate me, but they’d be awake for school.
Back in the 00’s, when Travian was big. Travian was basically Clash of Clans with worse graphics. I’d go on holiday with a girlfriend, and I’d have to pop in an internet cafe every 2 hours to spend resources or my city would be fucked.
