For me the best part of X-Com is when you actually learn the mechanics of the game. When you learn the missions that aliens do, recognize how the ships look like. If you see three-four supply ships on the ground you know they're either resupplying or building a colony. Do you attack the colony, or harvest the supply ships that come regularly? Look at the chart. Seeing extremely high alien activity in some remote country? High odds there's an alien base there.
