Having basic features like split screen, or even the settings themselves, locked behind progression walls.
This one is kinda specific to Bethesda games but fast traveling to a point only to have to load again because it put me right outside a door that is a load screen instead of putting me just inside that door so I only have to load once for the actual fast travel.
Not having an FOV slider.
Constant bullshit popping up on screen. Damage numbers, kill streak messages, onomatopoeias, etc. That shit is distracting as all fuck.
Games with special currencies you can pay for with real money but can also be earned by playing, but limit how much you can earn by playing.
