If you set out to create a game involving collecting, or even looking at and cataloguing, a bunch of different fantasy creatures, you’re going to have some that are at least a little similar to pokemon
I think Cassette Beasts pulled off the Pokemon gameplay format without making anything that Nintendo could try and sue over.
When I got my deck, my instant library of things to play due to old Humble Bundle purchases was staggering.
My backlog would take several lifetimes to complete, and I still by new games because “sale!”
I need to DL all of them before society collapses and there’s no access…
“But there was time now…”
I feel that making a game exclusive can sometimes make better games, because you’re making one game instead of 2 or 3. Even with games that are on multiple systems, one version always ends up being “the definitive”, and the other versions are not up to the same standard because they’re put out just to appeal to a wider audience. Focusing on one system let’s you put everything into making your game great instead of making it accessible.
Pokemon didn’t grow up with it’s player base. They try and keep the storylines Kid friendly, when I’d guess 70%+ of players are adults.
Black & White probably had the most “Adult” narratives of the series, delving into the slavery/forced labor a bit. I’d love to see the games delve into some more adult themes, but I doubt it will happen.
I play a lot of roguelikes because I rarely have the time for a multiple hour gaming session anymore, and I can get a complete start to finish game in with a roguelike in 30-60 minutes. I think that may be part of the popularity.
I’ve played all the ones you mentioned, my recent vices are Magicraft & Star Vader’s, both on steam. Slay the Spire & The Binding of Isaac are two I always come back to during my “what should I play?” moments.
