No, it is funny seeing them in Warband and I know it brings some entertaining nostalgia for the BG2 veterans.
Also I make a lot more original maps than I make BG2 ones. I currently have 3 original maps in the mod, with one new original piece in production another in planning and a couple of old native maps I made that will be easy to convert. Along with plans to make a couple of the other BG2 ones which take me about an hour to make, which is real quick compared to new stuff.

FYI Battle for Asturias is made by me as well. As is Village Assault and Towton. However Village Assault is bugged because of the old and unstable house props that I need to replace so it is not played much if at all as some people crash.
