It reminds me of the days of the gen 3 Pokemon games. The coromon you can capture are well designed and interesting. My favorite part of this game is the quality of life mechanics like teleporting between towns/cities that have been discovered without needing a coromon that can fly. They also have custom difficulties where you can decide many aspects of your game, including whether you can catch trainer coromon or not. I enabled it because I like catch one of everything and I'd rather just catch them when I encounter them the first time.
This game is like if the creators behind borderlands and fallout came together to make a game. Decisions matter as you'd expect in an RPG, and the gun play feels engaging. I also like the companion system where I can have a mix of them travel with me as opposed to only having a single one at a time as is the case with other RPGs like Fallout and Elder Scrolls games.
