My fav cheese strat is the multiple engines speed advantage the player can ALWAYS gain on the AI. Being able to fly circles around the AI ships not only gives me an edge over the enemy in battle, but it is a lota FUN !!! The AI "cheat" I like best is how poor the major AI civs are at resource grabbing and how the minor civs usually grab a good % of them while the colony rush is on. I find it easy to take them from the minors with little risk of damamging eary game wars. The minor civs are just to weak to launch effective wars early in the game.
