While watching a review of \Beast of Reincarnation\ I was struck by the line "anothe game with dodge/parry mechanics because they're too lazy to think of new ones."
I enjoy parrying and dodging in hack and slash games, sometimes to the point that it makes those games souls-esque. I played a game without them recently, and it felt empty/missing. I remember a similar feeling playing old shooters where you couldn't take cover.
It got me thinking: are there any mechanics that are so standard now that you feel like you couldnt go without them?
Alternatively, are there any mechanics you remember from one game that never became mainstream in the genre?
For the latter, I really enjoyed \ME Andromeda\'s "profile" system. Instead of picking a class and leveling in it, you could freely switch between "profiles" at any time (including mid-fight) and completely swap your class. I loved the freedom that gave to mix playstyles and keep combat interesting all playthrough. Shame about the rest of the game, though.
