Predominantly male MC - I'll play a fem MC if it's a lesbian game and it's written by a woman - most men cannot write from a female perspective. It's just cringeworthy for the most part.
Unrealistic proportions
Sandbox just as an excuse to extend playtime
"Forced" LI's
"default" music - No, those stock music tracks you found do NOT enhance the gameplay in any way.
Relying on sound(s) for the game to make sense - some of us play with the sound off.
Non-skippable...
I always change the name, and always use the same one, irrelevant of the nationality of the MC. Makes it easier to realise when other characters are talking about my character, without having to try and remember what the name is in the current game.
It was a LONG time ago, so probably the original Leisure Suit Larry - something that'd barely qualify as "adult" these days, but was rather controversial back then!
