Each rating is out of 4. I've chosen 4, b/c if it's out of 5, you have '3' as the middle number and that's pointless. With 4, 1 & 2 means is towards bad and 3 & 4 is above average, worth getting.
Trophy difficulty: 2 out of 4
Comment: Slightly time consuming, but majority are easy
Music: 4 out 4
Comment: Includes the music from all the previous games and it gives you the option to play which music in each game. A good add.
Graphics: 2 out of 4
Comment: Pretty much the same as DW6, which is good, but they could have improved it in some areas.
Gameplay: 4 out of 4
Comment: There's more to do in empire mode than before. Both the option to become the emperor/ruler or an officer and various feature such as defect, swear oath with another officer, get married etc.
Additional info: Edit mode is a lot of fun and there's more DLC's coming to expand the costume selection.
Overall: 3 out of 4
