Well IMO a review from someone is what THEY think of the map and they shouldn't be sensitive to the mapper's style but lean towards what they, the reviewer, likes.
Anyways....here is my ingame review:
Lighting : 7/10 personally i thought the lighting was WAY too dark in many areas. If you brightened the entire map up to a .3 or .4 ambient lighting then it would have helped a lot I think. It would also get your player buildings, repair huts, and light towers to be a bit brighter as those are all based on the ambient light setting as you probably know.
I believe through a lot of work you could still get the same lighting using a higher ambient lighting but it would require a lot of work and editing of lighting and light posts to find it. But of course if you did your buildings wouldn't be so damn dark.
Detail: 9/10 The detailing was good. However, hard to see in-game in many areas due to the darkness of the map. But like said it was nice and there is much proof of effort. I also feel you could have done more swamp water areas.
Layout: 8/10 The layout was great IMO. A very nicely set up 8 player map. To the exception of the player start locations. Each start location was different which was cool....but there was an uneven amount of build space and in most cases not enough. Plus some places seemed easier to defend than others.
Also. I found 1 cliff error. It is where you have placed a 4 way road piece as a corner and have those end road pieces coming to the right, one of which is sitting on the place where there needs to be a cliff connector. This error is in the upper left near the player start locations. If you can not find it then I will get a picture of it but as of right now I am too lazy to do so.
Triggers: 8/10 Many triggers on this map. I loved the patrol in the top right city and the ion storm was nice and long which made things challenging. Though I felt there could have been a few less meteor triggers. I think about 80% of your triggers were meteors and at some points this caused my game to lag when a good portion of them would go off at the same time. A better computer would easily go through it with no lag of course but i just felt there were too many of them. It seemed that throughout the entire ion storm i just heard "meteor storm approaching" or whatever the thing says when a meteor storm is coming down.
Game-play: 7.5/10 Gameplay with 7 AIs set on level 2 was very nice. There was constant movement which I found nice. But I found the amount of mutants and other various resistances on the map to be too much and would slow down players too much. In fact the visceroids in my 3rd match on the map crippled 3 of the AIs I played against. (provided those were weak AIs) But still I think the amount of neutral resistance could be cut down.
Overall: 7.9/10 A good map really. You have certainly improved on your mapping abilities. Your cliff ramps/slope set pieces are much better than in your last map for sure. Now if you fix that cliff error and brighten it up just a tad bit or perhaps add a day/night loop (though I know you said you don't like those) then you will have my vote for a spotlight. It really is a very nicely done 8 player map and I do suggest this map for play. The minimap looked very impressive when I first say it. So great job.
