Honestly this. I’d love to maintain my own database of music, but streaming services did something right to make it so accessible.
Prices will need to hit a breaking point to scare people away, and even then they will keep using the next easiest thing (e.g. YT Music + ad block in my case).
There has been several game “mechanics” that have been patented in the past. Two examples I know off the top of my head are “overhead arrows that point in the direction of the destination” and “minigames during loading screens”.
That said, these were applied for specifically as patents in the US, and every other game made does not go through this process (especially since I doubt that this would worm in this day and age… I hope, wtf is going on across the pond) especially for entire game concepts, and OP is definitely in the clear.
