I was one of the matrix beta testers. I had played some of the demo when it first came out in 2006, and had no intention of buying it.
I play a ton of war games, all WW2 and some modern. I look for games that focus on tactics or strategy instead of mass rushing, and where I can figure a way to beat the AI or multiplayer games with an unusual strategy or tactic.
I actually ended up being very interested in this game, much more to it than I orginally thought.
I play this game very much in the mode of looking at how I want to approach different capture target areas, I move untits in small pieces using terrain, and given the terrain what units types I will use for the attack. I move units in steps very piecemeal, but with an attack plan. I play the game at the half speed setting.
The enjoyable parts of the game for me are the large maps, the ability to use artillery, air force and paratroops in conjunction with my main land force, the need to be careful not to pointlessly waste units, and the way the AI will counterattack from the flank or in rear areas.
Much to my pleasant surprize I've found it very interesting to work through how to plan for the counter attacks and how I want to conserve the available forces and use the force mix.
I suspect many people will play the game using the bull rush methods, and not see the other pieces.
I expect to be playing it for a while, and getting into the editor. For me it fills a niche, that I haven't found in many games.
