Somebody asked about SEIV on the GalCiv forum [topic subject: "So, was Space Empires IV any good?"]. Of course, I had to post my opinion, but most of the replies are lukewarm to negative. If anyone wants to contribute [politely, I hope] to the discussion, go to:
GalCiv
and post your opinion. You'll gave to register with the forum to post, but that's easy.
