Agree that the actual monster designs looked dull. Funnily enough in a "new pokemon" kind of way. Other monster collecting games like SMT and Digimon seem to manage to produce more interesting monsters/pals/demons.
Why did you so casually dismiss it? Just because you don't like a game doesn't mean it's boring with a lot of faults. The game was at 20k players average on steam last month, putting it above valheim, bdo, rimworld, risk of rain 2. That doesn't really speak to me as a boring game.
Just because it has a lot of players doesn't mean it's good. I mean, recently, one of the top 5 games on Steam just a few days ago was a literal scam. (The Banana game)
My opinion, but I like Palworld more than any of the 3D Pokémon games since X/Y. It's not really the same style of game when you really get into it, but the things that make Palworld different make it outright better to me. I don't plan to buy Pokémon games at all anymore, and Palworld is a significant reason why not. It's a little dismissive to suggest they aren't a threat.
They wouldn't have a leg to stand on legally, but it puts me off that a lot of the designs are just blatantly copycats. There are great monster catching games out there with actual original designs that would kill for 5% of the attention Palworld got.
