The new features of battle for Sicily sure sound appetizing. I always like mods which add extra realism and elements of managing your army (like who will lead the vanguard, who will lead the rearguard, and improving or decreasing relations with other lords based on this). Hiring mercenary captains that have a chance of betraying you would also be nice, especially if said captains could betray your enemies as well and come over to your side.
Well, I'm day dreaming now, but I still trust in Nijs to bring us a smashing mod, like Battle for Sicily has always been.
Go Normans!
