People didn't hate 1UPT just by chance, but for two reasons:
1) the AI was not able to use the system (it makes it incredibly difficult to move the various units optimally without creating traffic jams)
2) the System requires more extreme micromanagement (you have to line up the melee units in front of the launch units and the cavalry units on the flanks, but the map was much narrower than necessary given that it simulates continents while the units simulate a division that should stay where a combined army would fit) creating a move here, put there, move this way situation which is quite annoying.
So much so that the complaints surfaced once the game was released and not before
