yeah if you don't have a trick to get super duper cheap renewal its less and less worth it, similar to netflix/disney+. I have years stacked thanks to microsoft rewards and burning free monthlies at gamestop while they allowed it.
its pretty easy to just resub for 2-3 months a year around Oct, play everything good, rinse and repeat. I think stuff like Forza Horizon 6, The Alters, Doom Dark Ages, etc make it interesting but its much closer now to "well i can just buy the 3-4 actual good games at discount instead of subbing and I can buy it all on steam or PS5 soon".
it would be cool if microsoft made a deal to get xbox on switch 2 or steam or PSN (unlikely) but i doubt any of that will ever happen. it'll be interesting to see what sony and microsoft do to counter switch/steam deck popularity, both have portable devices in the works but who knows how powerful, what OS, how usable, backwards compat, etc.
