Well, just load up that kikdm6, run around. And then load up dm2, run around. What do you think? Really, do it guys and girls. :)
I've been trying to say it with a lot of words above. :/
Atmospheric, kinda pretty too, and interesting, functional usable architechture (i.e. prettiness isn't just some fancy brushes with clips on that you can't interact with them, although prettiness can also partly be just decorations). I mean prettines you can run on top of, hide behind and under or shoot through. Or all of them. Just use.
And not too bright lighting.
In dm2's case, one can see that it doesn't hurt if there's some lava, a few buttons that do something (crush a player at ya, or open doors or lava walkways or a trap). And bars through which to shoot the rocket (or hit the bars, just check near water) or a few narrow places where you can harass the quad-rl-guy (like below quad). A few moving platforms. The challenge of rj'ing from bigroom to the moving platform or risking a trickjump to get the gl & mega from the other side when the platform is coming your way. Or shooting people while on the platform.
Maps don't have to be numb and dumb and "easy-going" with just pretty ornaments.
Many of your (meaning this community) singleplayer maps are great and have functional and interesting architechture, it's just mind-boggling why the dm maps mainly are so much different when they really needn't be.
If you happen to make dm-maps, make NOT like this:
That's my feeling. :)
Now, I know that the dm community is ultraconservative and it certainly feels frustrating from a mapper's point of view (I know, even with just this little experience of this terradm) to try to get even _some_ reaction on a new map.
One can consider it like this:
You can make a good single player map that gets played by 1000 people once. Or you can make 1000 dm maps of which ONE gets played by 1000 people - but 1000 times. - same expectation value :)
Ok, ok, enough ranting. This is all just my personal opinion that I felt had to be said. I haven't checked all already-made dm maps and I still have many to look at when I have time. (Have to lessen this forum-writing and also mapmaking.)
