I really like it. Steer clear if you aren't interested in a game with a revolving cast of characters though, your entire party will change up every couple of hours due to the game's design of killing people off every 2 years in-game. I was really crushed when the dude I spent an hour making in the initial character creator just passed away after like an hour or two of playing. :'(
It's kinda roguelike-y in nature. Dungeons themselves are fixed, but the ones you get on your territory are random (also they're god damn huge in size). You're meant to go into other people's clan territories (or the offline ones the game provides) to explore, as well as get hitched with other people's characters. You can share characters and some equipment online via QR codes, which is pretty good. I'm already on like my 7th generation of characters since I made the initial three you start the game with.
