Driving fast in vehicles forcing wider turn radius instead of keeping roughly the same turning speed but the threat of sliding out or rolling over.
Forced linear paths, invisible walls, non dynamic physical combat based upon a psuedosimulation of the physiology, mental, and physical state of the character that does not take into account weight, gravity, and momentum (something euphoria could theoretically subvert), scripted plot forwarding events, no choice, health bars, and physically fit characters that cannot dynamically climb obstacles in the environment. - Everything that has atrophied while graphics got better to the point that not being able to do even a third of the above is jarring to me.
kill walls.
Not really a mechanic but games whose gameplay do not fit the atmosphere.
Not having the same abilities as depicted in cutscenes.
