You're essentially saying that if you get landlocked in a small continent, reload because you're dead. That doesn't seem to be helpful, either. I suggested that vendur start off with King because I have been able to win landlocked, small continent, no Maritime, few river starts, no AI on same continent on that difficulty level. Before you start knocking that, I suggest that you try it as well. It's not as impossible as it sounds.
Now that I've done it, I feel confident that with some tweaking, I can win on the same start on Emperor. Eventually, I hope to be able to win such a start on Immortal. Once I'm on Deity, I can have something very concrete to offer, but until then, I can suggest that the OP start working on the problem at a level he can manage.
