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.
