I didn't find it too hard to control, actually used to enjoy playing it alot, back when all I had to play was my ps1 and gameboy
I found my C&C retaliation for ps1 and played it for a while, It was actually pretty difficult but playing with the link lead against a friend is fun, also handy that it came with 2 discs.
The time when I played this game it was really awesome. I am still playing the Command and Conquer series, but I would not mind getting Command and Conquer Tiberian Sun again and the skirmish of the game is also really awesome I enjoyed playing it.
