Isometric perspective in modern RPGs. I can forgive it in older games like Fallout or Baldur's Gate because at the time, isometric pseudo-3D graphics were probably the best choice they had at the time, but times have changed and now it just feels needlessly constraining to a camera control freak like myself, its only virtue being the retro appeal that is lost on me.
On the other hand, if the game is not aiming for photo-realism, but more the formal representational style of say, chess, then the visual clue is useful. It says "do not make assumptions based on reality, it might not apply here." Does Tetris need to look like real rubble?
What I don't like is when they mix-and-match conflicting things like that in the UI. Games that strive for realism, but put floating health bars over enemies heads, or worse than that, numbers. It's OK for the Player Character to have a game HUD for things you can't visually evaluate otherwise, but keep it minimal, and use a game-related style, and at least try and provide a reason for it (as in Fallout). Blood-spatter on the screen is OK if I'm logically wearing one, such as a visor, space-suit etc. but not if I'm bare-headed.
I'm on the fence about the glows that Skyrim spells add to affected actors, as you could expect magical effects to show somehow, and fire, frost and shock have reasonable target effects, so the other spells deserve something.
tl;dr no unrealistic realism.
