I downloaded and tested it out. I played the first one as Liu Bei, second as Lu Bu, and third as Sun Ce. Heres what Ive found to be annoying.
-Pollution isnt gone... Maybe you should back up the timeline to somewhere where we dont have that problem... because its a real pain in the ass.
-Whenever I send out large amounts of offensive units to attack... they get demolished before they even reach their target... the enemy always wears away at my forces because offensive units have so little defensive power and whenever I send defensive units along to counter this, the offensive units get killed first and all thats left is the defensive ones. This is probably worse than pollution.
-Ive noticed that sometimes, even the weakest beings can defeat my officers at times. I sent Zhang Liao against a MILITIA, Elite Zhang Liao, defeated and didnt even inflict a single bar of damage. This is just... appauling

I think that we should have the element of a major defeat, but not on such a small scale. This is like a common peasant defeating highly trained soldiers... its just not going to happen.
-Wei is just too strong. As Lu Bu... I initiated a coalition of every ruler in the game against Wei. I took Puyang Chengyang and Qingzhou, Liu Bei took Wuchao, Yuan Shao took Guan Du. This all occurred within 3 turns. 3 turns later Liu Bei was annihilated, I was pushed back to Xuzhou with only Lu Bu left(this is when Zhang Liao was killed by a militia), and Yuan Shao had lost all claims to Cao's lands and some of his own citys. Li Jue and Zhang Xiu were crushed in no time, and Ma Teng and Yuan Shu were being threatened.
-Armies are too weak as well, but I have to say that the new Siege weapons are very cool... siege towers especially.
-Im not quite sure if you meant this, but on the regular "Ships", it has the hanzi for "Ice" on the sails. Is this purposely there or was it meant to be rather... umm... contradictory?
-The new unique officers are cool... they die far too easily however. I was attacking Liu Biao as Liu Bei, I sent out Zhang Fei with all of my minor units to attack Danglang(should be Dang
Yang). He and his units were all wiped out within 2-3 turns.
-Again, Yiling was west of Jiangling, and as I suggested in all of your other scenarios... it should probably be renamed either Jiangxia or Xiakou. Either would do fine... as when Liu Bei fled Dangyang slopes(Chang Ban), he called upon Liu Qi for help who was stationed at Xiakou/Jiangxia.
-Guanling should be Guan
Gling. You forget the G in the middle.
-I noticed this in some other scenario's and dont know if you changed it or not because Im not looking at the map now, but Wuzhang Plains is Wuzhang Yuan, not Guan... if you did... oops... sorry.
But I really like the map, it gives the feel of an ancient watercolor map... very oriental looking. Thumbs up, lots of potential here to be a top scenario for Civ3.
