My advice is; still waiting a few months and you buy it at Christmas, when hopefully much improved.
In detail:
+ Good graphics
+ Unit diversity, compared to Shogun 2
+ Harmonious design
+ Placeable equipment (barricades, traps etc.)
+ Lots of good ideas (unfortunately the implementation is often inadequate)
(Combined land and sea are here purposely not!)
- Long migration periods (partially 5min, for some even longer)
- Graphics gliches
- Poor performance
- Verbugte Buttons
- Lack of KI (even for total war conditions)
- Moderate balance
- Wrong sounds are played (eg we have destroyed a tower when taking points)
- Wrong tooltips
- Partially bad UI (eg time to time small to large windows)
- Capture the Flag and in open areas
- Objects are partially misplaced (eg floating forts)
- Faulty collision detection (eg driving through country vessels)
