The game is going through so many changes and evolving so much. That if you had a chance to play the beta a month ago. It's going to be completely different on the next patch. They're implementing an overworld, crafting, more interesting quests.
Yeah I'd agree on that now definately, as when I first hear of the game around when it started closed beta testing, it seemed pretty uninteresting. Now that's it's later as well as looking at a more info, it seems better, and interesting, although still has some unappealing factors.
Considering that it's free, I may try it out on release, or perhaps even open/closed beta.
