Seriously, there is a difference between "unplayable" and "buggy". "Unplayable" is a game that is either so ridiculously difficult you cannot do anything significant without devoting your life to it, or a game that has so many bugs, problems, and disruptive "features" that it is impossible to play in its intended way. "Buggy" is a game with a few major programming flaws but is otherwise still beatable without unrealistic amounts of effort or is at the very least enjoyable without being overly frustrating. Most gamers today would consider NES platformers "unplayable" because of massive hitboxes for enemies, massive jumping puzzles, or unrealistic time restraints; these are valid claims. In DF Adventure Mode, which is what you seem to be considering, the combat system works fine, if the physics are a bit silly; interactions with NPCs work fine, and the bit about civ sites is both easy to get over with and takes two or three minutes to fix on your own anyway.
Seriously, get your priorities straight, man. If you feel the current system is too buggy, play Cataclysm or Nethack or something to get your fix of rougelikes for a few weeks until DF2014 comes out.
Also, ignore the people who claim that DF2014 is unlikely, they're just making dwarf jokes. As Knight Otu said, there are only three more bits of features left and some minor debugging before we get a steaming pile of !!=Dwarf Fortress=!!.
