Hi all !

I'm new here and don't know anything about modding :)
I hope someone of you people can help me with my questions !

Well here's the thing ...
I want to create a multiplayer campaigngame (prefer in warhammer) for me and my friends.
Why Warhammer ? Because it will be a 'game of thrones'-campaign with of course the DRAGONS !!! :p

Soooo how do i start ?
Whitch programs do i need to make nice lannistersuite or beautifull khaleesi dragons that breath fire ?
The looks are more important then the stats.

ps. i dont have a good pc or the game, i just want all the information first :p
