Who offers a similar service to Xbox Game Pass? Especially the Ultimate version.
The only things Game Pass Ultimate has over PS+ Premium are:
a) PC and Console dual inclusion,
b) Day 1 access to first party titles,
c) Access to EA Play.
The PC element only matters to a
very small subset of people who game on both Xbox and PC, and the access to day 1 titles hasn't exactly been stellar -- with a lengthy drought between games. Pentiment, Hi-Fi Rush, and Redfall aren't exactly system or service sellers, even though Pentiment and Hi-Fi are good games. Sure, Starfield and Forza are coming this year but the day 1 element is heavily dependent on
actually getting games out, which Microsoft has a poor track record of. Most of Sony's first party games end up on PS+ Extra and Premium eventually with R&C, Returnal, Horizon Forbidden West already there. I'd expect GT7 and GoWR there by year's end.
As for EA Play, you could add the EA Play subscription to your PS+ Premium subscription and it would
still be cheaper than the retail price of Game Pass Ultimate, even at Game Pass Ultimate's old price. $150, combined, for PS+ Premium and EA Play vs the old $180 annual retail of Game Pass Ultimate (which will be $204 once the new pricing goes into effect).
If you don't think PS+ Premium is a direct competitor to Game Pass Ultimate, you're either trolling or a blind fanboy.
