One of the major difference here is that game platforms have a relatively less power than Apple/Google in their current business practice. It's usually game platforms that tries to attract game developers/publishers into their platform (sometime with strong incentives and even subsidiaries) to win the market and publishers are the decision maker; the same thing doesn't usually happen in the app store case. Game devs don't have much incentives to sue platforms as long as there's competition between consoles. Note that things were different in the NES/SNES era and there actually was a number of antitrust cases for Nintendo. But honestly, I feel that competition within a single game consoles should be allowed. This doesn't have to take a form of side-loading (which obviously has a significant downside of piracy which hurts game devs/publishers even more than monopoly/monopsony) though.
