Lots of games are also called Roguelike. Based off a game called Rogue. The makers of Rogue do not get to sue the makers of Hades.

Pets that fight for you, including being able to store them for portable carry has been done by many other games, including Ark. In fact, playing Palworld made me compare it more to Ark than Pokemon: base building, automation, catching dinos/animals/monsters of different varieties for different uses. Some can fly, some run, some can be used as parachutes. Some help automate actions at base. There is a tech tree unlocked by leveling, starting with primitive weapons and moving on to guns and higher caliber guns. Blueprints are common in ark for higher quality crafts to build at, you guessed it, crafting benches.

Collecting wood, stone, metals, etc. Also the animal assistants can help there too, but only certain ones. Also, Ark has cryopods for storing your animals/dinosaurs. You even throw em to release.

If they had exactly Pikachu or something it’s one thing, but similar games are just part of the business.
