Firstly, let me say that this is a great game. Its predecessor was good fun, but was looking very dated. Fortunately AoWII has bang up-to-date graphics, superbly strategic gameplay, a cunning AI, a great campaign and an interface thats simply a joy to use.
Ok, Ok, so you've probably figured out its turn based by now. If you don't play turn based games generally, but fancy the idea of pitting your whits againsed EXTREMELY cunning computer opponents in a game of strategy, this could be for you. Especially if you liked any of the Civilisation series, of which AoWII incorporates many elements. In fact there are quite a few elements in AoW2: City Building, Resource Management, Diplomacy (both internal and external), Magic, technology development, military expansion and religion all form part of the game-play to a greater or lesser degree. The default game mode is 'simultaneous turns' which allows for real-time gameplay to a certain extent. Players can react to one anothers decision in the same turn.
The fantasy setting is very well implemented, with colourful, truly jaw-dropping graphics, decent sound and music and loads of ambient animation going on. You don't expect a strategy game to use a lot of graphical system resources, and as long as you have a 16Mb 3Dcard (yes, thats right, a 3D card!) AoW2 should run be fine.
Theres 20 or so (great) campaign missions, roughly the same number of equally well designed stand alone missions, and a mission editor. With a burgeoning on-line community churning out new missions and campaigns of exceptional quality, AoW2 will be on your hardrive for a long time.
