I understand where your coming from on pushing the editor to it's potential. I used to love just messing around making landscapes in Ued. I used to do a bit of mapping myself... in fact, I'll give a little background on my story.
I got Unreal 1. I started Unreal Engine mapping on a Cyrix 200 mhz system with 16 megs of ram - but I didn't want to do the normal DM maps everybody does nowadays, I wanted to do original stuff, which was the killer. Originality takes detail, and my system could hardly handle it... later I upgraded to a 350 mhz AMD k6-2 with 128 meg ram and a junky vid card, and still couldn't do what I wanted. I left the Unreal Engine scene once UT came out, as I couldn't afford any new games at all, and I was getting fed up with the "lets all have gay anal cyber sex in IRC and act like h4x0rs" attitude with the entire community. I came back after a long ways away, with the 436 patch released IIRC. I caught up on the INF updates, and checked up on Serpentine (which I thought was way better than INF back in it's day
). I cranked open Ued 2, became disgusted, and vowed never to make a UT map. Instead, I'm waiting for Unreal 2
So, I improved on my texturing skills (using PSP 7 and then later moving to PS 5.5 - both have advantages), and became a texture artist. Much easier on the system, and I don't have to play the game to be one
And that's about it. People in the UT community still haven't grown up, and there are still a lot of guys in the #inf community who have a ways to go too.
To sum it all up, go ahead and make sweet looking maps
Expression is something few people actually do, and those who do it should feel free to do it without limits (/me looks at his 4000x4000 photoshop graphic files folder). I'll be sure to d/l this next one and check it out
