Apparently the board size is 2x2ft for small games and 4x4ft for larger games.
I also had a look through the booklets to work out what weapons you get on the sprue...
Coftyrans get 5 Harlech (the long thin rifles), a Cryfen LMG and 2 Doru SMGs.
Crusaders get 4 Bogen (Assault Rifles) and 3 Ryshi (Heavy Rifle).
For the Coftyrans this allows you to build a Yawdryl (leader), Trench Raiders (potentially), Sharpshooter and Rhyflers (basic troops).
While for the Crusaders this allows you to build a Yawdryl (leader), Rhyflers (basic troops) and LMG Rhyfler.
For both factions there are only a couple of options from the Rhyfler's Pocketbook that you can't build...as far as I can see. Looks like a fairly solid set of options.
