Then you should go and check TA Spring. It has all the good stuff from TA + modern graphics engine + terrain changing mechanics.
I remember this epic duel I played vs 2 other guys (yes my teammate quit) in a castle type map. Since I turtled too heavily for them to break through, eventually they just drowned me by blasting me with arty long enough for map's floor to erode beyond water level.
There are a few, some quite novel, and they're getting better. For example, one of the new ones exploits the computer's ability to individually micro dozens of scouts to repeatedly pwn your mexes at the beginning of the game.
