That's flavor lore-wise. Bad things happen in the story, that's all. The Dungeons' Explorable Mode is insanely hard, though.
Oh. I was expecting to have lose-all situations.
W/e, sounds neat. World of Warcraft is way too easy (Dungeon/Raid wise), so I hope this game offers a challenge.
Edit: Might I add that it comes out RIGHT when college starts up again for yet another semester.
