It's neat to see that most of the responses so far are relatively similar. Most seem to be a bit weak in the mapping/art department, but strong in dialog and ideas.
On the plus side, mapping is something that is pretty easy to pull up a bit with some practice. We have a wonderfully helpful community here, that love to offer help. (Dalph, any tutorials you feel like doing on mapping, I am sure will be greatly appreciated!)
I looked at some of my maps, even the ones that I thought came out pretty well at the start, and I compare them with some of my new maps. I can see big differences. I have always wanted to learn some form of artwork, which I just don't have the talent for. Even after taking 3D modeling classes in college!
As for me, when I get going I do pretty well at mapping now. I feel I do pretty well in dialog, and I can do some nifty things with eventing. While I can't write scripts, I have gotten a little passable at being able to read the scripts.
I do pretty well at balancing encounters and have made a spreadsheet that I will be sharing with the public soon.
Music... yeah, I can't make it at all, but I can visualize where it should go in a game.
For those of you that have trouble with cutscenes... do you just hate them altogether, or hate trying to make them?
