Newbie: Which PzC game to begin?

[Outlaw Josey Wales]

I was going to mention there was also a Kharkov 42 and 43, Rhzev 42 and Budapest 45. You really can't go wrong with any of the titles whether EF, WF, Med or Modern. Just grab whatever floats your boat. If the game system suits you, it won't take long before you find yourself owning several titles.
