So after playing the demo and reading through threads here, especially the manual, it appears that most things only have 3 upgrade levels. Some need a tech level 4, but most are a 3 it seems. So is there really any point to getting your tech level up to 5 or 6 or higher? I mean, realizing I could get tech levels above 4, I was sort of hoping that things would have more upgrades that just aren't available in the Demo, but that doesn't appear to be the case.
So is there really any point to getting tech level's above 3 or 4? Am I missing something?
Help is much appreciated for the newb.
