Unless players have elected to fight a scenario that requires otherwise, games are played to an agreed points value for each army. If players agree to a 2,000 points game, this means that each player can spend up to 2,000 points on his army. He cannot spend more points but he may spend less. Sometimes, it's impossible to spend all the points, so a typical 2,000 point army might contain 1,998 or 1,999 points. This doesn't matter! The army is still a 2,000 point army for the purpose of determining the characters and units available.
