Is there such a mod.

Hello everyone, new to the game, very sad/upset.... I don't mean to sound like a crybaby or anything but, When I bought this game I though there would be castle sieges and what not, where you control one castle build it up, make troops attack and defend, you know the traditional rts games (I have been wanting to buy one for 3 months now, family isn't rich so money doesn't come easy) So after saving up for so long, I have the money to afford one, I see medieval 2 total war...looks promising like its just what im looking for (Yeah stupid me for not reading the details...all my fault) so I basically buy this and its not what I want, I want to be able to go online make a settle ment fight ,raid, siege , not just gather a million troops and go head to head, is there such a mod where I can do such a thing...or should I basically start saving up again, if so, suggestions would be nice

I think you probably are looking at a different type of game in that case. Like Strongholds.

The closest you get to that in M2TW is playing custom battles where you are either attacker or defender of a custom settlement.
