I have played the game for a few hours and most everything seems to be working fine so far.  The beginner AI hasn't done anything that could be considered at threat yet.  However, after a awhile i reached the end of the research tree and with nothing to research the game wont let me advance turns anymore with out choosing a research of which i  have none to choose.  i tried looking for an option or something that would keep let me advance but haven't found anything.  Other than that i like what we have so far.
