Tetris kind of has a long running title on this topic.
I dont even like tetris that much, but it has captured the attention of generation after generation.
It’s probably one of the only games you could open in almost any setting and have people wanting to play it.
Nintendo does takedown like this all the time. I haven’t seen anybody actually point at evidence of fraudsters, and there is no reasonable benefit to doing this as a fraud. There is no avenue of profit.
