If they implemented it they would've 100% been sued to the point of bankruptcy lol. It was so dumb-

oh good night cya

edit: ill research tmrw, im tired as heck

(i sorta remember it being cancelled)

It was pretty bad of a personal experience while I was learning it tbh, it was hard-carried by documentation, tutorials and the community who have mostly now moved to godot.

Unity tried to implement a pay-per-install fee, which wasn't even well-defined and didn't even talk that much about how it would actually work. Basically, everytime someone would install your game they would want you to pay them a undefined fee. When they announced they were about to do this, it destroyed the reputation of the company forever. It's funny because it would've destroyed those f2p mobile games, which was likely what was making unity the most money at that time.

NOTE: they don't actually pay any developers (unless they made/published some games themselves, or if the dev uses their ad program), the developers use the engine to make money and pay unity a share of their revenue from the game. I don't remember them suing anybody over it since it never actually went into effect, but they might've idk.

I also don't think any games were deleted, since the devs would lose a lot of progress. A good amount of studios stopped using unity for any future games, but after the fee was dropped, a good amount stayed because they already developed skills and a whole workflow with the engine.

inevitably it ended up with some game devs deleting their games and im not sure the status now of their terms
