DOTC... I loved that game. It depends on who you play to an extent, but I remember there was always a spot I'd aim at on the screen with the joust and I'd usually do ok at it. Unfortunately the disk drive on my amiga doesn't work anymore so i can't exactly load it up and tell you what part of the screen I was actually aiming at.
My advice is just to avoid jousting, because majority of the time your bound to lose.
Wow, that was a pretty worthless post.
