The Cossacks series is a pretty decent one on the whole, offering historical real time strategy shenanigans that make a pleasant change from the usual science fiction and fantasy offerings such as Warcraft and Command and Conquer. Back to War is actually an add on to the European Wars main game so if you are a fan of that game, then this is a worthy addition to an already solid experience. The main game is set in the 17th and 18th centuries and allows players to take control of a variety of European countries and their armies, each of which with their own unique weapons and units, including naval ones. Back to War doesn't add much to the base game, but what's there is certainly appreciated and provides fans with some good content to get their teeth into. This includes two more nations (Hungary and Switzerland) with some interesting units which provide some new challenges even for fans of the original. There's also some new architecture, again specific to each country but that's about it really. However, what's here is pretty decent stuff and the new nations and units certainly add in some flavour to proceedings. As this is an expansion pack, the graphics remain as decent as ever, with nicely detailed environments and units that have a lot of character. The interface too is simple and intuitive so even if you haven't played the original, it's a breeze to pick up, while the missions themselves are varied and challenging. The other games in the series are equally worth checking out so if you fancy a change from sci-fi and fantasy, take a look here.
