I’m familiar with Googles policy stating that apps deployed to Enterprise / Managed devices won’t require developer verification.
Non OEM Device Management apps are registered with Google Enterprise, so they are known apps with known signatures. They aren’t really classified as sidesoading, they are considered to be their own app store.
Steam has Train Valley 2 as my most hours by far (3544). But a lot of those hours are from minimizing the game, and leaving it running overnight, so probably closer to 2000 hours.
This is mostly due to the Steam Workshop / community maps, as there are hundreds of them and new ones get added constantly, so it’s a great game that I can play quick sessions while watching something on TV at night, or eating lunch at my desk.
Red Dead 2 has 2400+, but 2200 of that is on Xbox, and it’s the main thing I play on Xbox, so I’m not sure if that’s actual gameplay time, or just “game running but just sitting at the main menu” time (which would be a lot of hours).
Oxygen Not Included is over 600 hours, and I haven’t even added any DLC, so I see that getting a bunch more hours when I have time.
