You can't play Skirmish with more than 16, in my opinion it don't suit this game, and you only get 3 maps, they are trying something new, Red Orchestra and Rising Storm one never had this option as far as i know, this game is brilliant in big battles with the full sound effects plus you get more maps, Skirmish ain't terrible but 16 men????? it won't take off sorry, you may as well just play Battlefield or Cod if you want that, they do it better but Rising Storm does the big battles better, just look at all the 64 man servers they are bouncing at the moment this game is rocking, loads of full servers, maybe Custom servers will let you do something different i don't know.
