I bought this game in December (with a 15% Matrix voucher for being a customer for 4 years .. quite nice).
It's very easy to play (even for the number of counters, but a turn is definitely do-able in an evening).
It's not so easy to win, even on easy difficulty versus the AI.
Here is an animated gif of my successful campaign as the Germans, with standard (historical) starting positions:
This game ran from 22nd of June till 1st of November 1941, when I took Moscow (the game ends with a german victory when you capture Leningrad, Moscow, and Rostov (with Kharkov also being under german control).
What is most interesting about this is the additonal layer of operational decisions and the personal relationships and the politics involved in this endeavour. I would very much recommend this game. It's not perfect, but still very good entertainment and it strikes the right balance between complexity and playability.
If anybody is interested in a PBEM, I would be up for it, I can play both sides.
