Fr, Nintendo isn’t going to get any more money out of people not using Nintendo addons. Instead they basically lose free advertising and make people dislike them even more. Shooting themselves in the foot again.
If Valve does ever make HL3, it’s going to have to be ground breaking. Every Half Life game redefines what gaming is capable of. Eg HL: Alyx was an insane demonstration of what VR can do. I do think it’ll happen eventually, and may even partially be in development right now. But I don’t think we’ll hear anything about it for a very long time.
