Stadia needs more games.
I know Stadia is still new but I'm a pro member and I always look every month to see what games are released and it’s mostly cartoon or 2D games which is something I don’t play or look forward to.
I’m not a hardcore gamer but would still would like to play big iconic games like Batman, Arkham Knight, Spider-Man miles moralis, gta and more shooting games even if it’s old existing games.
You can look forward to Sekiro: Shadows Die Twice possibly launching next month and then Star Wars Jedi Fallen Order in November along with plenty other major releases to follow. Those won't be a part of the Pro lineup but currently there are some offerings that might suit your interest such as the Metro series and even more currently on sale this week.
Hope there are plans for Hogwarts Legacy, Harry Potter has a huge Community
