Is there any idea whether Doom (the one before Doom Eternal) will ever be available on Stadia? Another question...will games like Fallout 3 and The Elder Scrolls Skyrim ever be available cause that would be superb to see.
There is no public roadmap about upcoming games on Stadia. The publishers are in charge to bring games to the platform. Maybe you want to ask them if the plan such things.
If you will recieve any information, please let us know!
