Extremely cheap for 4 campaigns in a game.

User Rating: 9.5 | Medieval II: Total War Kingdoms PC
Medieval II: Kingdoms is the expansion pack to Medieval II. This expansion however is no ordinary expansion. 4 new campaigns in just 1 game, the campaigns also aren't short ones too.

Teutonic Campaign: This campaign focuses on the Holy Roman Empire's aim to conquer the areas surrounding the baltic sea. However you don't play as the HRE until you unlock it. 8 factions will appear in the game with 6 being playable and 2 unlockable. Gameplay is fun and exciting.
Rating: 8.5/10

Americas Campaign: This campaign focuses on colonization of the New World. New France and English Colonies will appear in the game. 10 factions with 8 playable makes this one of the best campaigns in the Kingdoms expansion. Rating: 9.3/10

Crusades Campaign:
This campaign starts a few years before the 3rd Campaign and focuses on increasing Christendom in the Holy Lands. 8 Factions with 6 playable.
It's the best Campaign in my opinion. In this game you'l be conquering more often and there will be many battles but that's all part of the fun ;)
Rating 9.6/10

Britannia Campaign: This campaign in my opinion is one of the most difficult. Keeping Public order will be hard as each faction has a different culture. 6 factions with 5 playable. Neverthe less this campaign is still fun and good. Rating 7.6/10
