Oh, I see. I thought you meant early game. That sucks really bad.
I was wrong, there is probably like another 25 hours of gameplay left because of this super hard end-game dungeon with 20 floors versus the regular 6 (maybe 8, still have 1 more to go before the last one) and they are adding new areas and cities. Undead Labs is adding a ton of stuff, and hopefully they will add a reset stats token or something. Anyways, you will love the game. Its casual, but difficult.
