with some tweaks here and there the maps would be great. Ortona has way too many statics to be playable, less occupiable buildings would help a lot.
Anzio was great, I feel less enthusiastic about Cassino simply because it was hard to identify paths up the bloody hills. for most of Diadem, i just camped one flag as defender because I was getting dizzy running in circles around the base of the hills.
In priority,
1) Anzio : playable, ready for public release (killer haystacks wtf?)
2) Diadem: playable, needs better infantry footpaths (it was easier getting around in the truck, kinda wierd IMO)
3) Ortona: needs work, and IMO not historically accurate enough. The Germans heavily defended Ortona with well emplaced men who fought to keep every obstructed street, which btw is a glaring flaw in my opinion (the shermans were owning a little too much).
As Aussen was telling Toddel "this map needs AAS"
All in all I would gladly replay every map if I get the chance to again,
