Solid strategy. Not the most in-depth one, but I've always liked how fluid the gameplay is for the most part in Close Combat. The new effects and sounds are a welcome addition, really brings the battles alive and the sound of a MG42 opening up is as terrifying as ever. The AI in combat is OK. I find it really depends of the scenario and difficulty. I stalled the Allied advance almost instantly in the Grand Campaign playing as Germans, but after playing 5 turn of operation "Digging in" as Allies, the AI is putting up a good fight. I also see improvement in the driving AI, it's still not perfect and tanks often swirl around like idiots, but once I ordered a Tiger tank to drive down a road just barely big enough for it, it did follow it flawlessly.
Some might say the graphics are dated, but I would disagree. This is a top-down strategy game. Graphics rarely matter in this genre, and I must say, it does look rather good compared to the older games in the series.
The only gripes I really have are the new mortars introduced in PitF. Basically, when you order your mortar to shoot at a target, it takes 20-25 seconds to aim the first round, 5-6 seconds to aim the second and after that it starts to hit very accurately. This is devastating if you are not inside a multistory building. Also, the MG42 is a bit too accurate in my opinion. Most german infantry squads carry one and they fire 8 rounds per burst, making the extremely effective against the Allied infantry.
But all in all, it's a very good game. Of all the CCs I've played (CC2 through PitF), I rank it among the best in the series.
