Re: Formative games
Hmm, good question. I think I've moved more towards the games as entertainment side recently, and am not sure if I have many that have affected me.
Two that spring to mind are The Path and I am Alive, which touch on some similar themes. Although The Path is just not fun to play, at all, it kept me fairly riveted in the first couple of hours. I am Alive made me slightly uncomfortable too.
