Well, there are solutions to have a PC in living room too. But right now, it’s not a good time to think about it anyway. When the prices were normal, I would have suggested a Steam Deck or Machine. Even a cheap Deck (launched at 379 Euros) would have been enough to stream from your local PC to the other room over network. The new codec by Valve in Steam is crazy low latency and good quality (but does not work over internet).
For the software as service thing, its not just like that. Nintendo gets money for every single game sold on the platform, plus for every single micro transaction. I wasn’t even thinking of something like PS Plus, and the one Nintendo has is dirt cheap and doesn’t offer the same value anyway.
