The AIs build well here, except for the island keep, which I'm assuming is meant for the player. I would give this a 5 if you made the island kind of bigger, since even I had trouble making a castle
I don't know why you say this map is unbalanced, It is balanced, without being TOO full of resources. But I like having to fight for the resources so if you put all the resources clsoe together I'll be happy, but it's already fine the way it is. ( I would have gave a 4.5 here )
Not a lot of 3-player maps out there so i guess this is a good one for triple-threats. And of course, not many beach maps either, except from you. Maybe if you tried making a "middle of nowhere" map? (If you did, tell me, cause I'm too lazy to look through all your submissions.)
Map Design: 4
This map is one of your better ones map-design wise, but if you spread the iron and stone around square by square instead of in clumps, and put some trees around, It would look better.
Well there's a line. If there wasn't anything at all I would give a 2 since its a skirmish. But maybe some instructions or hints? I'd give a point more for that.
A good map, one of your better ones like I said before. Keep practicing and you'll be a great map-maker!
And could you review my map "Guarded Remains"? You know, return the favor? Thanks!
