This game is looking really promising. If you were a fan of Rune Factory, monster catching games like Digimon, Harvest Moon, Monster Rancher, etc. this game may be a dream come true for you. It's going to have many many many features, including farming, monster catching, romance, online cooperative multiplayer, fishing, adventuring with real time combat, and more! I'm personally very excited for this game!!
Currently, it's running a crowdfunding campaign on Square Enix Collective (Crowdfunding) and is doing pretty well. https://collective.square-enix.com/projects/346/relegend/
