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.
No matter how many I may start, I always end up focusing on just one. I also find it difficult to get back into a game after I have stopped playing it for while, so these days I try to just start only one.
