no i'm not suggesting it anytihn i'm simply stating what does happen when you clear out the monsters. In my current game, the middle of the map had most of the monsters, there gone and now there is half a dozen diffent coloured boxes representing the different a.i. players outposts and occasional city. the colours are constantly changing now that there's all out war (by my instigation).
IF the monsters patrolled more effectively but in tighter areas, (except for the weaker ones which should roam more freely), then the A.I. and the player would have to expand slowly. Point A: i have not seen monsters ever attack an a.i. Point B: even if they did, which would be good and would ease my shard/wild recourse owning fears somewhat ----> Everyone = poor = slow and with minimal (i stress minimal) magic available to cast at enemys, use on the map and summon units. HOW is that a good thing? My point is this: IF, they control City Spam; With monsters, new A.I. or some other method or combination, THEN they will need to streamline the following: Structure Building, Unit Building, Research, Mana growth, Income, Population Growth etc..... Seriously, the game is slow. OK its a 4x game, they're never fast, but they aint that slow either, and the ones that are, never do as well. M.A.X. (a not fantasy) turn-based game had a long build-time of buildings, but those buildings all built something or provided research, allowing the game to pick up momentum after that 15 (light facory) 24 (heavy factory/air factory) turn investment. Elemental does not do it that well, or does not do that, and the buildings that do speed up research, build speed etc. need to be researched themselves, then built for many many turns. Having several cities, shards is one of the few (only?) ways of negating this hideous snail slither.
