if you want an open world RPG, you can try justice league heroes, lightning returns: final phantasy XIII and odin sphere.
This 2 games are not fully playable, but odin sphere is your best choice, but the music in the game is very loud, and sometimes it's getting hard to hear what's happening in the game, and the game has many things to do, including alchemy, cooking, and some more.
I am now at chapter 2 of the first book, and right now I am struggling to fight the mini boss, it's really hard to kill because it can do a move that will poison you.
going in to the wilds, collecting pokedex, and capturing them are my kind of thing,
training them, making them evolve, and generally making them stronger is my ultimate goal,
fighting other manamon tamers, winning the tournament, and fighting octoros are what these manamons like to do,
and ultimately, I become the master of mana!
