I have to agree with the common sentiment, and I believe the topic is justified. Such an overhyped, overreferenced game, and why; I've never known.
It felt less strategic than C+C, provided more frantic, larger battles.. Yet TA provided larger and more interesting battles, on the other side of the spectrum.
It sits in the middle, a moderately entertaining, well-presented simplistic RTS with an sufficient if highly clichéd storyline. No special merits, simply a fun game with a lot of cinematic exposition, firmly seated in it's place as a 'classic RTS', even before it's age caught up with it.
Blizzard followed the same route with Diablo and it's sequel; simplistic but well-presented, fast paced, lacking any strategic depth, taking a genre and 'simplifying' it, for the mass market previously too intimidated by stat or strategy heavy games of either genre.
Warcraft, of course, took the same route again, replacing the hardcore space marine/alien setting inspired by the Alien franchise and Games Workshop's Warhammer 40, with derivative fantasy - while mixing the two genres with some minor RPG elements (of the gather potions and defeat named monsters sort).
And World of Warcraft took precisely what made earlier MMOs popular, mixed it with a little Diablo 2 and the storyline and setting of their own previous project, Warcraft 3, and provided... The quintessential simplistic and repetitive MMORPG, a phenomenon more social than gaming-oriented, providing a daily grind, the illusion of purposeful endeavor and an easy way to make new friends.
Blizzard work in a very well-defined fashion. They are very much businessmen, rarely innovating with new features or coming up with original material, but taking established genres and settings and polishing them into what will achieve massive market success.
Clever from a financial standpoint, but personally, I've never bought a Blizzard title for more than £5, second or third hand.
