Most of the time I find people who miss TA miss nuclear arms races. That glorious 10 minutes of screen shaking in the late game when hundreds of nuclear missiles fly back and forth and we get to see who built enough strategic defence.

Our games usually devolve once we hit the unit limit, since we're too lazy to find that 5000-unit patch from the old days. From that point, we go for nukes, berthas and targeting facilities, or just massive air waves.
We really should try out SupCom with more than a couple of people. My guess is that it would be a great fit for the types of players we have. (-:
Yes, definitely. It's the truest successor to TA, and in the same spirit. It retains the flux economic model, upgrade-by-building, powerful UI features (building group templates are awesome) and a plethora of options on how to optimise your work.
Plus the whole vast-armies-of-destiny thing. I have very much enjoy games where it devolved down to 16 megaunits vs 150 strategic bombers ...
