It will be out in January--for me, I thought it was a flavour of both, to be short and quick. All you do is mass things in AI War, IMO and you will win. Unfortunately, there's not an equivalent of ghetto gunships, though.
Engineers? I will usually increase my numbers after acquiring a few more planets before researching T2 for the teleporting--I keep the two in the beginning, and then perhaps increase the number to ~10.
Thanks for joining the community, Mavor! Any another questions, or wanting coop via IRC/forums (IRC: http://arcengames.com/irc/aiwar_irc.php) feel free to try and arrange one for yourself. (:
