Nice music.
Poor character design (been spoiled by DW series):
Zhao Yun looks awful. Nothing wrong with the character model, just the character design. His spear is offensively inconsistent with popular design.
Guan Yu is missing a cape. His crescent blade's blade is too big and ugly.
Zhang Fei's pose looks ugly.
----------------
My DW rant aside, the IAP is not bad as I thought. There's coins and beans (IAP). Coins are earned through normal gameplay as end mission reward. The coin income rate is alright (~100g per mission [~2:30]) for the first two levels. Permanent items cost between 3k - 15k with a good spread between the two numbers. The only health recovery item (100% btw) costs 550.
The gameplay in short, is DYNASTY WARRIORS on iOS!!! In other words, button mashing greatness with damage numbers

. Battles feel exactly like what DW is, except with smaller, and thinner mobs. It feels like a DW lite without sacrificing what makes DW great.
There's a virtual movement pad that works pretty well; a block, normal and charge attack button (no musou

). There are 3 skill buttons and possibly an item on the side.
The graphics are great, with compromises on my iPhone 4. There's slight but noticeable stuttering (and some flashing graphical glitches on enemy models), so the gameplay is not perfectly smooth. However, it does not detach any enjoyment out of the game.
The music is great, and amongst the best three kingdoms music, with suitably bombastic and loud symphonic arrangements.
Final verdict: a slightly technically flawed product, but a great fix for DW fans.
*Edit: @Lawliet
The attack speed is just on par with medium attack speed DW characters. Though the stuttering I've mentioned does create sense of slowness.
On a side note, this game needs a musou attack (Turn-A's nuclear bomb combination musou attack in DW: Gundam 2 comes into mind

).
