looks ok. I hate twilight decoration though. Not your fault though! :)
One big problem, the northern nats are so much closer to the mains than the southern ones it's sad. At the same time the southern back expos are so much farther than the northern ones. I don't like this tradeoff, it is a positional imbalance, I would rather you used inverted ramps for mains (and for the back expos if you can, I've never seen a sunken ground inverted before. It wouldn't have to be perfect looking if it functioned perfectly).

If I'm playing t I'm not using those islands.

Gas issue, north have optimal on 3

This reminds me of a playable Twilight DF.

I don't usually use inverted ramps. For the top base entry I didn't use them because they just aren't that good. If blizzard wasn't gay and made inverted ramps that came standard then I'd use them. The ramps supplied in the Map DB are definantly crafty, but I prefer the standard map ramps.

I wish there was a good sunken ground inverted ramp though, because it would make it more even for the backdoor expos.

I'll make a change on the top bases to see how it looks.

Updated, I think that fixes a positional imbalance. I don't really think it is similar to DF... I can't fix the top imbalance because there is no good inverted ramp for sunken ground, I tried earlier for about 45 minutes and gave up.

You can also open the center a little bit. You can surly do this whitout any problems.

Blah, I used copy/paste to move that to the center because I made it too high so it'd be frusterating. What are you talkin about LGI? I mean, usually when I make comments I see something in my mind of how I would like it, how are you thinking would do better? I know it needs to be opened up a little but it is kinda hard. I can't open up the sides because then the paths to the side bases are too close.

See GMCS.

I'm not quite ready to give up on the bridge tile just yet ^_^. I made the bridge much larger though and opened spaces on the outsides.
