Caesar is trying to expand his territory. Sure, it would be a lot easier if the viking aren't around that time. Both Roman and the Vikings share something in them. Both of them want to conquer the land and no one would give up on their claim. In this game, you be Caesar and you need to lead your troops to victory. It means that you need to destroy the stronghold of the Vikings. As you make some progress, the game would be harder. For instance, you would run out of funds and you need to send some men to the minefield to make money. As soon as you are making money, you can then send some troops to the battlefield.
