World Zero

It's an RPG Maker game that isn't inspired by Earthbound! (I never played Earthbound)

Play as Shouta Kitano, travelling through the lands of a dying world in a parallel universe and save the world by bringing the core to the underground facility made by his dad. Through his journey, he will make friends that join his quest to get to the facility. He won't just meet new friends, he will also meet a strange man who tries to stop him from delivering the core by sending some hired mercenaries.
