I remember TA very distinctly - my brother was very good at it, I’ve always been hopeless at RTS games.
You’re right - 3d improved the game. However outside of examples such as this one , I feel that it generally took a while (15 years maybe ?) for game designers and coders to eventually find a middle ground , as in use the latest technical fad, but still make a game that is pleasant to play and better than without the technical fad.
