Spencer says that console players have been "streaming 45 percent more" on console and "24 percent more" on "other devices."
The service is separate from Game Pass and offers "free ad-supported cloud access to some games," but a launch date remains unknown.
Premium subscribers can play Commandos: Origins and Microsoft Flight Simulator 2024 starting today on PC, cloud, and Xbox Series X/S.
Game Pass Premium subscribers can also access Ninja Gaiden 2 Black, He is Coming, and Eternal Strands from October 15th.
Xbox’s latest Game Pass price hikes have left many longtime fans frustrated, raising doubts about the company’s current direction.
The tier will allegedly support Xbox consoles, PC, web browsers and handhelds in a public beta before fully launching down the line.
Meanwhile, Premium subscribers gain access to titles previously only available in the Ultimate Tier, including Abiotic Factor.
Premium now retails for $14.99 and instead of day one, subscribers will experience Xbox-published titles within a year of launch.
"The majority of partners who've had a game in Game Pass want to bring their future titles to the service," says Chris Charla.
RoadCraft is out now for Standard and Ultimate subscribers with Deep Rock Galactic: Survivor and much more to come tomorrow.
We Love Katamari Reroll + Royal Reverie, Wargroove 2, and All You Need is Help will also be leaving the service on September 15th.
Citizen Sleeper 2, Orcs Must Die! Deathtrap, MechWarrior 5: Clans, and more are also coming to Game Pass Standard on August 6th.
The Ascent and High on Life also return to the service while Square Enix's Legends of Mana and Trials of Mana debut for the first time.
The two companies are teaming up to "co-engineer silicon across a portfolio of devices, including our next-generation Xbox consoles."
Other notable titles include remasters of Warcraft 1 and 2, Rematch, Against the Storm, Call of Duty: WW2 and much more.
Microsoft Gaming CEO Phil Spencer also confirmed the return of a classic that's been with the Xbox brand "since the beginning."
Warhammer 40,000: Space Marine - Master Crafted Edition, FBC: Firebreak and The Alters are also available in the coming weeks.
Monster Train 2, Tales of Kenzera: Zau, to a T, Symphonia, and Spray Paint Simulator will also roll out in the coming days.
Other notable titles include Dragon Ball Xenoverse 2, Dredge, Teenage Mutant Ninja Turtles: Mutants Unleashed, and much more.
Microsoft Gaming CEO has "always thought" about the subscription service as "just another option for somebody who wants to play."
