Okay so work with me a little here. You’ve just been tasked with recommending a game to someone who’s got very little experience with gaming.
Maybe they’re a kid who’s just starting out, or maybe they’ve just never had much interest in videogames.
What one game are you giving to them to show what videogames can be
Movie-like games where you pick choices? Life is Strange, The Walking Dead and similar, Heavy Rain.
Also Lego, Thrine, EDGE for easy platforming.
It’s also worth noting many games now have a “story mode” like difficulty, an easy mode with almost no risk, just something to allow you to experience the story.
What comes to mind is the Uncharted series, though I would probably try to avoid any sort of 1st or 3rd person shooter like game with the typical dual stick controls.
