I've played a few hours now as well, it's a lot of fun and much easier to play than HoI 3. I would recommend all of the grizzled grognard types to steer clear. The game is way too streamlined and user friendly for you
Only complaint so far would be that the AI can certainly do some very silly things with troop movements and I really don't like how military access works currently.
I'm playing my first game as Romania. I went fascist and then attacked Bulgaria (I mean, why not?) to get some extra factories and such. Then I lined up against Hungary. I really should have lost that war since my army got all but pocketed and then Hungary slipped a dozen divisions into Romania proper. Instead of going for my undefended capital they were happy to loiter in the north for several months, giving me time to reach somewhat undefended Budapest, forcing them to capitulate.
A later oddity was when Germany attacked Poland. The Soviets did not attack Poland and the Molotov-Ribbentrop pact was still on. They instead attacked Estonia, who was allied with Poland, which for some reason caused 50 German divisions to travel around Poland and into the SU, then they reversed course and then 50 SU divisions cruised into Germany. Then Germany won against Poland, then the next day declared war on SU, leaving dozens of SU divisions hundreds of miles from supply. So, yeah, some work to be done there. Or AI Hitler is just a very sneaky trickster.
