They dont matter in theory for home consoles aswell. But, this time around because american companies got such huge relevancy on the market last cycle, they are now in the position to block the Japanese companies if they dont do their bidding. Basically what happened to Nintendo. They block you out of the engines and you get no third party support even if the third parties would like to release the game on your console.
There is an unseen bottleneck on this american dominated market and that is that there arent many engines available because its too costly to develop one. This means almost everyone is force to work with Epic and the unreal engine.
