Actually, the counterstrike makes a good example.
Each round isn't a whole game, but is in fact just a round.
After the victory conditions are met, (# minutes, # rounds won, # kills, etc) you compare scores and see who won the game.

You then change maps, begin a new game, and everybody starts from scratch.

When you do well in a round, just like doing well in a big fleet combat, you end up with some advantage over your opponent in the next round. But once you've conquered all and been declared the winner, its back to square one plus only a golden trophy to hang on your ego.
