It's good in my opinion, but it depends on if you like really long games or not. I swear I'm probably 10 hours in (OK maybe I'm exaggerating a bit) and I've pretty much mapped 5/30 floors so far. It also gets annoying when you forget a Warp Wire and have to walk all the way back. Though apparently later on there's gonna be Warps and stuff 'cause there are symbols you can use to mark your map.
I also like it 'cause you get to create a guild (/guild obsessed) and a team~ Only five people can travel with you, and two classes are unlocked later in the game, but yeah.
