I'm primarily a PC gamer with a library slowly approaching 1,000 games on Steam. While I have sometimes bought games through the other storefronts like Blizzard, GOG, Uplay, and EA Origins, I never really invested significant time in them to the point where I don't keep track of what is in those libraries. Suffice to say, I thought that I was so entrenched in Steam that I couldn't possibly play in another storefront for any meaningful amount of time.
This has changed for the past year. I hopped on one of those deals that gave me access to Game Pass since Microsoft added all the Bethesda games and partnered with EA Play. And I gotta say, I'm invested now. Invested so much that I bought a Series X despite having zero interest when the new generation of systems was announced. Game Pass on Xbox is an even better deal than Game Pass on PC. The library is larger and for the games that are Play Anywhere, I can continue my save file on my PC when my living room TV is unavailable.
I really think that Microsoft has a winning strategy with Game Pass this generation and it really surprised me how my attitude to the Xbox ecosystem changed this year. While I think both Sony and Nintendo have great exclusives, the value proposition for me of convenience and a rotating slate of quality games will likely keep me invested and subscribed, moreso than Xbox Gold or PS+ have in the past.
