I don't suck at them as much as I have no love or tolerance for the limiting and overly dragged out style of gameplay. It's not that I hated Ogre Battle at all, I just loathed having a damn battle take 3+hours to do (minor gripe being no direct control.)
I think really RTS's spoiled me because ever since I did Dune 2 in the day for MSDOS I have had next to no tolerances. I prefer when having a so-called war to be able to move my troops in battle as I see fit when I want to, like a real war works. The concept of turn based fighting where you can move, then fire your next turn, and so on I have no love for at all. Originally I found in games like Military Madness I didn't have much issue with it, but later titles I found the CPU AI was well stacked against the human player so that the CPU could see through fogs of war, just knew where you were with inhuman precision shots only a person could do on a wild guess, and other tardish behavior. I think it's the only thing in gaming I hate more than the lovely rubberband ai games like Ridge Racer popped into driving games.
