I'm a veteran SHO/MTW/RTW player and have just got MTW2.

the danes are a fave of mine from MTW and in m2 look pretty good early on (like before).

I'm still early on in my game (most advanced unit i have is the dragon boat), but the key to winning with these guys is to expand early and to keep the HRE happy and your friend. Unmarried pinces and princesses come in handy here. make some diplomats and get them busy selling alliances and trade rights.

make taking hamburg, oslo, stockholm and stettin a priority. make a push for antwerp and bruge if possible as well. all these are decent moneymakers and will serve a good springboard for an attack when someone breaks an alliance.

I am building up forces, waiting for someone to break an alliance, to do this, i plan to leave a city lightly defended to suck in a army to try it on. considering doing this with bruge, as it has antwerp not far, as this will be where the relief force will come from and i have france and england sniffing around.

the early danish troops are great. norse archers are excellent (not bad in melee) and the unmounted carles are great and relatively cheap for the punch the give. a few lots of these making a charge have made mincemeat out of anything they have faced.
