Well, after 9 gigs of downloading- I finally got to play medieval total war 2. Now, i played the first one a long time ago- and i loved it. This one lives up to my expectation. it is a great RTS with an unmatched campaign. though you can only play as 6 kingdoms on the campaign and in total there's around 30 factions. there are many different types of units- they are mostly all unique for the major factions apart from the peasants and the basic foot infantry. it has great graphics for the time- and with a good enough computer you shouldn't have any troubles with playing it.
The battles are great and you don't really worry about the men you lose cause its cheap to get them back- this is great. unlike in some games like Mount and Blade Warband where you are devastated if you loose troops because it takes too long and it is very expensive to train them again.
one bad feature of the game is the tutorial- the voices are annoying and they tell you things over and over again.
I give this game 4/5.
