Hmm, interesting question, Mike.
I think one of the biggest problems is that we have so many people who do such incredible work. For instance, I have seen so many BF-109s that look like miniturized versions of the real thing, that I'm almost getting bored (for lack of a better term) of seeing them. Yes, the craftsmanship is outstanding, but I'd rather see something different.
I'd rather see a rare model subject built straight OOB, than another highly detailed popular subject. Don't get me wrong, I love seeing what people can do with the 109s, 190s, 51s, 40s and 47s, etc., but seeing the same kits with the same AM kits is getting a little repetitive.
Maybe if we had more people with my particularly sad skills, things would be more interesting. You know, then we could have threads "what did this model used to be - plane, car, boat or armor?"
