The combat is very lacking vs previous titles.
Cons.
1. The voice acting is subpar.
2. The story is ok but it could have been stronger.
3. The weapon upgrades aren't really worth it as the combat is basically just spaming one button or waiting for a parry to insta-kill.
4. Vendor's lack depth and inventory.
5. The investigation tab is a mess.
6. The advancement of abilities are really plain.
7.very small map in comparison to previous titles.
8. Your eagle is not really usefull.
9. Lack of weapon variety.
PROS.
1. the details in the cityscape and buildings are awesome.
2. Eagle vision works well and is usefull.
3. Npc are well done, they seems to be going about their day and have their own agendas
Overall I feel that it was a game that started out really good in development and was then rushed to finish.
Needs more polish all around especially with the interaction between npc's
I can get over the small things like the weapons not having sheaths, I mean come on how does the dagger not cut your belt, and the sword swinging wildly around your side without injuries.
Also one of the blacksmith was holding a red hot piece of steel with her bare hands while hammering it!
I feel they just needed more time to develop this game to the standards that previous Assassins Creeds titles set the marks for.
