Cheat. Build lots of towers. Build backup buildings in case your originals are destroyed. Send your troops on raids, in two or three parties each. Have them round up mercenary camps, gold mines, and possible sites for harvesting lumber, as well as crushing any enemy encampments. Then, lead a final, incredible assault against the enemy base. Keep manufacturing new units and sending them straight into the fray. Have your heros use their most powerful spells. Then, u win.
It's all very easy once you cheat.
That is, if you're playing against an AI opponent. If you're fighting a real person, then cheating is immoral.
