The presence of all these "goodies" (valuable artifacts and structures) becomes meaningless because, geographically, it's faster to reach the enemy than to reach them (meaning the enemy will be defeated sooner). Also, the neutral creatures controlling the entrances/exits to player territories are weaker than the armies guarding the "goodies." Thus, both reasons indicate that access between players is faster and less problematic, which means the game will end quickly, and the aforementioned "goodies" will remain unused and untouched (this is what happened to me: a Necromancer broke through to the center, infiltrated the Warlock's territory, and I defeated the Necromancer, taking both the Necropolis and the Dungeon. Then, a Demon emerged. While I was taking the Dungeon, the Demon infiltrated the Necromancer's territory. Now, I'm planning to defeat the Demon and reclaim the Necropolis, then I'll take out the Inferno city. The result: the Dungeons remain untouched, as does the center of the map with the desert (I only fought the golems in the pyramid and about 30 devils).
Conclusion: the strength of neutral creatures needs to be reduced, except for those controlling the entrances/exits to player territories
