Probably the most satisfying real-time-strategy game I've played in a while and this from someone who is sick of RTS.
The best way to describe how this game plays is that it takes what the latest Star Wars RTS game -- Empire at War -- tried to accomplish and perfects it. It almost feels like the PC classic, Syndicate. Technically you're playing an RTS, but it doesn't feel like one. Resource gathering, structure building and unit upgrades all have their usual place in this game, but the awesome battle spectacle that plays out before you, the emphasis on WHERE your units are (i.e. take cover behind anything), the destructible environment that allows your tanks to roll over and destroy anything as well as explosives to demolish any building, and then the fantastic cutscenes with small history lessons on D-Day just make for one of the most enjoyable WWII experiences in gaming history.
If you remember the last scene in Saving Private Ryan where they have a limited time to fortify a bridge leading into a town and then must holdout against a German invasion, well, you pretty much have the scenario for half of the missions in this game. These aren't boring sandlot scenarios. Sometimes you must hold out on a hill for 30 minutes with what seems like impossible odds, sometimes you must defend 3 bridges leading to a French village and repel the Nazis tank invasion, and sometimes you must do the opposite and repair a bridge and raid a town in a scenario that automatically starts you out on strategically inferior ground. Everything is based on real WW2 situations that the allies faced in Europe so if you're into WW2 history, you'll get an added kick out of this game and I recommend you follow the game up with Call of Duty because it's a shooter that follows many of the same roads and towns in this game.
What's even more amazing is that I have yet to experience the online play which I'm sure will provide its usual addictive gameplay that has helped boost the RTS genre in PC gaming. I just completed the game, attempting to win the optional medals in each campaign, which provides more of a challenge for any ambitious gamer. The game also comes with skirmish mode which I'm sure I'll play a few times. This is one of those games that had such enjoyable levels, I played them a second, and sometimes a third time. ESPECIALLY as I went futher in the game and realized the pros and cons of all my units which ranged from snipers to various tanks to jeeps to mortars to engineers and so on.
This game will never have the hype of an Age of Empires or Warcraft but you're doing yourself a disservice if you don't buy it ASAP! I've played very few RTS games that were this enjoyable and it's one of the few PC games that has me eagerly awaiting a $30 expansion. I hope there's an equally brilliant mod community out there that adds even more to this classic!
