I think that is the main point of the lawsuit, if developers sell their game on Steam they can’t sell it cheaper somewhere else. If Value gets 30% the developer has to raise the price a bit to compensate and they have to raise it everywhere. Outside of sales I don’t think most games that are not on Steam are much cheaper elsewhere, so not sure how this plays out.
Open ended games, like Minecraft and NMS , can be really hard for people who only play ‘on rails’ type games to wrap their minds around. ‘Whats the point?’, the same one as in living your life.
Also, personal opinion, Stanley Parable is NOT a game. It is a walking simulator with a bunch of bad philosophy thrown in.
