I feel like there is a distinction to be made between abstract violence and "realistic" violence.
Many board games are based on violent themes, such as war, but at a very abstract level - chess, Stratego, Risk, etc..
Video games have become more and more focused on non-abstract, realistic violence.
To equate violence themes in abstract form (chess), or slightly less abstract form (Mario's jumping), with realistic violent viscera seems... odd.
On a different note, the classic Ali Baba and the 40 thieves was interesting in that the game allowed for and suggested playing through the adventure without harming a single creature. It was essentially a top-down battle focused exploration game, which was interesting for 1981.
