Personally, I kinda like your long map.
I always liked how a great distance could generate some interesting attack, and defence scenarios.
About 2 years ago, I set up a map similar to this, but it was in a + formation, to accomodate 4 players. With water being in the four corners to seperate bases.
But, it had to be played as a UMS, because I didn't want anybody traveling over the water and doing a drop, or air attack. So the appeal was never really there for my friends to play it, they were more into the melee at that time, than a trigger map.
On the subject of triggers, you may want to rethink that Victory setting a bit. If I remember right, with that particular configuration, both players would have to have exactly 35,000 ore, and gas, at the exact same time, for it to fire. No more, no less. Also, both would be told they had a victory.
If you were after a victory for the first player to get that amount of $$, change it to....
Current player accumulates at least 35,000 ore and gas
Then the victory setting.
Looking good,
