Missions continue to be boring, but gameplay/pace improved.
(Mostly agreed with Gamespot review)
Visuals:
Good, mostly same as Mark of Chaos. Improvements include faster pace of battle, so that battles actually look more exciting now. Units charging seem to have more of a visual impact too (regiment runs faster, more units fall over when charged at).
Unfortunately, castles/cities/towns still look rather bland.
Audio:
Same as Mark of Chaos. Nothing noteworthy, but not horrible.
Gameplay:
Faster pace of battle. Makes things less boring.
Unit attributes and abilities displayed and explained in "unit profile", so that you now know what each unit has or is capable of (eg. giantslayer, skirmish etc).
New units for existing races:
Empire mortar
High elf white lions
Chaos marauder horsemen
Skaven plague priest
Unfortunately, the single player campaign remains boring, as described by Gamespot.
General conclusion:
I gave this a rating of 8 because it really does improve the gameplay of the original Mark of Chaos. In fact, this is how I feel that the minimum standard of the original game should have been.
The main improvement is the faster game pace, which really makes a big difference (it often felt very boring in the original game). It makes events actually look more like real battles.
