Split Fiction has a couple of mechanisms that make it accessible for people who are not experienced gamers. There is a general "reduce damage done by enemies" setting that make dodging attacks unnecessary. If you get stuck on something, there is a "skip to next checkpoint" button. This is very helpfully for the one or two really oboxiously hard parts. This is an improvement in accessibility over the developer's previous game It Takes Two.
I'd highly recommend Split Fiction, both for its game play and story. It is also superior to It Takes Two in that there is no part where the games "to continue playing, press X to dismember your daughter's anthropomorphic stuffed animal to make her cry". That was a jarring and unpleasant shift in tone for an otherwise mostly light-hearted game.
