With all these new factions come new units and the previously mentioned technology tree. One of the most noticeable changes is the lack of religion, well people are religious in this game but there is nothing like the same amount of importance placed on it. The technology tree as you can imagine is not quite as high tech as the Medieval version which included gun powder units, although there are some similarities as catapults feature in both versions of the game. There is one real advantage to having a dark-age technology tree, you can't use the same tactics in Viking Invasion that you used in Medieval Total War. Basically are almost getting a new game for a fraction of the price of a sequel.
Believe it or not, all the above are not the greatest additions to this expansion pack. The Vikings themselves are easily the best addition. The Viking faction enables you to move by sea with ease and invade any costal area. The Vikings are the masters when it comes to battles at sea their boats are far superior to any of the other factions. This all makes for some extremely aggressive force and more importantly the Viking faction is great to play.
Another bonus you get with the Viking Invasion Expansion Pack is three more factions to play with in the original Medieval Total War game. These faction are the Aragonese, Hungarians and the Sicilians. If you're up for a decent challenge this is god for you, because these three new factions only have a small amount of land and their neighbours are pretty hostile. On top of this the game play of the original has been tweaked and improved, plus there are some new additions to some of the factions units. These new additions to the original game will make things slightly more interesting for a short while, but long term there is nothing here that will keep you coming back after you have completed the game, but they are all welcome additions all the same.
Fro anyone that has the original I would highly recommend purchasing a copy of Viking Invasion, it will keep you one your toes as far tactics are concerned and the Vikings are a really great side to play, you can be as aggressive as you like. It's also good to have a smaller map the game play is much less stressful and hurried more easily managed. In fact Viking Invasion expansion pack is a great addition, you get much more of the same in quite a different way.
