alt Hacker News> Game publishers have already publicly floated the idea of not selling their games but charging per hour. Imagine how that impact Call of Duty or GTA.
MMORPGs have had monthly subscription fees for a long time.
For a lot of games if they charged by the hour would probably see less revenue...people buy tons of games and then barely ever play them.
You assume there's only one type of player. Some players fall into a category I lovingly call Madden Guy. These people will play some other games, but they will play one game *a lot*. Call of Duty, Arc Raiders, Destiny, Battlefield, Fortnite, these are the type of games who attract these kind of players. If a game has 600 purchasable items, a seasonal battlepass-type thing, multiple female rappers skins, and a publisher-financed pro scene, it's probably one of those games.
Those games 100% already have game modes you pay by the hour. They will have special modes you access with currency and you need to keep paying to keep playing. Those modes are usually special, with increased and unique drops.
