Oh man, I put so many hours into Spring via Balanced Annihilation. Filled that missing part of my soul that TA and SupCom left, but SupCom 2 (an otherwise really good, but casual and much smaller RTS) didn't.

Also, we don't speak about PA.

Zero-K is the ultimate TA-like, IMO. BAR is really good but much less ambitious and much closer to the original TA gameplay, Zero-K has really cool terrain deformation stuff and interesting units
