When invading an enemy continent in civ III it is useful to land your troops on a mountain, thereby giving them extra protection against enemy counterattacks.
However, historically the majority of landings have been carried out on flat land. I suggest therefore that landings should only be allowed on grassland, plains, deserts and tundra.
This gives the defender an advantage (historically exact) and therefore makes considerations before an invasion much more interesting from a tactical point of view and would require a more intimate co-operation between different arms (naval support, air cover...). Also, this would give paratroopers an opportunity to step in, since they would be able to land anywhere and establish a bridgehead...
