SimBase
The technique in strategy war games of sitting back in your base and never attacking anybody so you can build up your technology and defences. Then you attack only when you have researched every upgrade and have a massive army at the end of the game.
I could tell that my opponent, SSJ4SnakeKilla007, was sitting back and playing SimBase, so I simply took all the resource mines in the map and then rushed him with overwhelming numbers of inexpensive troops.
