Thanks LDiCesare for clear instructions. That could fix it well. I think the "problem" is that the normal tectonics map often creates very large areas of plains and desert without rivers or lakes. This creates a more demanding strategic situation (and I think it is realistic) but some players find these parts of the map dull - particularly if it cripples early development. I like your "more rivers" solution, because it could make these areas more fun and usable, but does not risk the map simply becoming more like the maps propduced by the original Civ IV map script (which would defeat the purpose).
