1 - Out of memory error fixed
2 - Better spawning of resources on start
3 - More options in editors
for #1 aside from the bug the thing I would actually like to see most is a quick start new game with current options thing so you could keep randomly generating until you had a decent starting spot.
for #2 it would be nice if you started or had the option to start in a place with at least 5x5 tiles open to build and at least one food, metal, gold, tech, arcane and either horses or wolf tiles dependent on faction (you know the kind of spot you would actually want to invest some of your essence into beginning your rule in)
for #3 mostly more weapons and armor styles in sovereign creation and more clothing/color options for both sovereign and unit design
lastly having the town creation ability's show the 5x5 and open building area when you go to create them would be awesome or if they just cleared the area for use.
