I have to say I agree with Zig on this point.  I made the point before and even planned on building the Unis but put them off for the build up.  Sure we're killing them in tech but getting to those more powerful units and the space race techs will only make the game end swifter.  The 5ish turns spent on Unis will be more than made up for in more advanced units sooner.  Heck, it can even mean that we can drop science spending so we can upgrade all our attack units in one fell swoop. 

I also think ending the game sooner rather than later would be ideal.  There is no way Alpha can beat us in a space race, especially since they wasted their Great Engineer on a Golden Age.  I mentioned this in my post that didn't make it yesterday but a focus on Space Race Techs and Production (that's the part that got lost) would get this game over with much faster than if we keep planning for invasion force after invasion force on Alpha.  I'm not saying we shouldn't use what we got and build advanced units but I think the focus should be on containing Alpha (burning cities when possible would be part of this but not the aim) and getting the Space Race Victory.  Building Universities, Observatories, Factories, Plants, etc. should take precidence over building units and ships.  But hey, that's just me.
