Fantastic game. Why?
1. zoom system means that you can scale what you see from the entire battlefield to the regimental markings on a single tank - vast improvements over the RUSE system as well, the funny counters no longer appear
2. each battle escalates as it progresses BUT unlike RUSE which had a semi Age of Empres resource system, units appear appear from off of the board
3. the whole meta-game, for the first battle you play you actually only have a few units available, you need to unlock others as you complete the campaigns, play other people e.c.t. - your strategy will therefore be reflected in your army, did you unlock the artillery, or the helicopters?
4. I am actually a miniature wargamer, this game is like an epic version of my favourite game in real life - 'Battlegroup:Kursk' - there is a whole supply mechanic which means you have to really plan your offensives, and defensive moves.
If you like strategy, real strategy, then you may just be looking at the best game ever, I cannot praise it enough. If you are not so sure then I have had friends who have played this game and not enjoyed it so much: it can be confusing, complicated and annoying at first, but getting past the learning curve is well worth it.
