There is more than enough content by now and it is updated every 2 weeks so the wait is not long between.Is it worth playing this game in its current state? I remember making the same mistake with ToN, which was halfway finished. But it had so much stuff you had to keep in mind and I forgot most of it, while waiting for enough new content.
Also, if I remember correctly, their games use ver. numbers as the % of completion. Is it the same here? With game being roughly 53% completed?
