Google recommends a 35mbit/sec connection for 4K Stadia streaming and they say it uses 20GB/hr of data[1]. Even at your high example of 100GB, that’s just 5 hours of streaming. I understand that the idea is to optimise for instant play but it seems silly to download enough data to cover the entire contents of the game potentially multiple times over a play through. Platforms like Steam, Battle.net, and consoles already allow developers to post staged installs where players can start playing a game before all assets have been downloaded. Stadia continues to look like a solution in search of a problem, where that solution comes with a lot of tradeoffs that I find hard to swallow. 100GB is also only 10% of 1TB, and I find it hard to come up with a concrete use for the other 900GB.
