Same as OP.
Jesus Christ I am bad at RTS games, but man do I love them. It doesn't help that I have a lot of friends who are very, very good at them. I have a strong tendency to just try one strategy, get invested in it, and then keep trying to justify not reacting to the situation with sunk costs.
My inability to play Total Annihilation is a running joke among certain friends. When we all played together, I would be building my base and right when I felt like I was getting somewhere, one of the other players would destroy my entire base in passing. Not figuratively in passing either - since a lot of units in the game have independent movement and weapons, someone would just be moving their forces toward a more threatening enemy, not even watching their progress, and then suddenly notice that there was a smoking pile of ruins along their path when they went to check on their army's progress toward the actual threat.
