Total Annihilation was my favorite game for years! It is a spectacular game. I would still be playing it, but I can't make it run correctly under Windows XP. Supposedly its possible, but I really haven't tried all that hard because I don't have anyone to play with anymore.

TA was one of the very first RTS games, about a year earlier than Starcraft, IIRC. There are hundreds of units available: air, land, even water, resulting in many different possible strategies.

There are thousands of maps available on-line as this game had a fanatic following in its day. Internet play is possible.

I can't recommend it enough. I still have all of the stuff including a hundred or so of my favorite maps.

Let me know if you get it, I'll get you going.
