>>41431902About identity of not-pokemon game... Make it literally NOT pokemon.
If you make it blatant, you'll be compared to a giant mega game, and I don't really think you'd want that.
Pokemon is a relatively contemporary setting where everything revolves around using and fighting pokemon. Make your clone something entirely different.
Make it cyber punk with robotic/cybernetic/bioenhanced creatures.
Make it fantasy with wizards binding demons and magical creatures.
Make it space adventure where you capture literal alien creatures.
These concepts also instantly invites to incorporate new ideas and concepts that further helps make the game unique.
Also, you'll need hot girls in your game!
