This is just a small list of things I would like to see one day. Not all at once unless it's possible, but all around a bit here and there would be nice.
Update the color coding, since Lego has new colors and way of color coding. "Dark Blue Grey, etc." Try to get things as accurate to comparison as possible.
Realistic Based Castle / Knights weapons. such as the "Gladius you already have, just more options like that." I know there are a few, but a "Pole-Axe, Claymore, etc."
Realistic Based Castle / Knights Helmets and Armor. would be nice. I know there are a few, and a good bit of them are AWESOME!! "HOPLITE / Officer Plume FTW!!"
Anyways, just alot more options on the Castle area.
I am a mideival buff. :P
