Over at TWCenter.net, poster 'Edric Storm' has put up some smart new Song of Ice and Fire house emblems. Whilst these are primarily for use in Westeros: Total War (a fan mod and conversion for Medieval II: Total War), they've been put up for general perusal and are suitable for use as forum avatars.
From top-right, the symbols for Houses Arryn, Baratheon, Frey, Greyjoy, Lannister, Martell, Stark, Tyrell and Tully, plus the personal emblems of Stannis and Joffrey Baratheon.
Meanwhile, whilst work is continuing on an ASoIaF mod for Mount and Blade: Warband, another ASoIaF-flavoured mod has already been completed. This one is for the popular strategy game Crusader Kings and looks pretty good, if you have a copy of the game.
