I bought it and am having a blast as well! There are definitely games I dislike, especially Barbuta (the first one). I get what it’s going for but eugh, too slow and clunky.
Magic Garden was the first game I beat - and it’s the only one I have a cherry disk on. Lots of fun, it’s not that hard once it clicks.
I’ve only went through the first ten games and my favorites are Magic Garden, Mortol, and Velgress. The latter two are kicking my ass, but I keep coming back.
It’s not even copyright, they’re suing for using things they patented, but their patents are extremely general. I kid you not, they have a patent for MOUNTING CREATURES, something hundreds of games have done.
I’m no lawyer so I can’t tell you how well this would hold up in court but it’s ridiculous. See more: https://patents.justia.com/assignee/the-pokemon-company
