What game features do you think are good/like or bad/hate

And don’t just say nodebuster likes as a genre, actual something unique part of a game that aren’t in every game.
For me I like stuff that give strategy like builds/skill trees where you have options , but if it’s not suboptimal to do it wrong, but there is a way to do it better.
But hate when a game has a wall that needs a certain strat to progress and get over it. Like a part of game that doesn’t unlock anything new until you get over a long boring continues part like the tower or pyramid from leaf blower revolution.
