Lots of interesting stuff to watch there. Not a lot of detail. I would love a good squad level WW2 game. I'm holding out hope for an Arma3 ww2 mod. The two main development teams have merged. Faces of War (Western Europe 1945) and Hell in the Pacific just announced it yesterday. Hopefully this will speed things along and we'll be able to play it soon.
I was reluctant to go through the complicated install process until I saw that video. I'll be buying this tonight and starting the install process ASAP.
The dev did say that the whole world would be included in Flight School but I think he means in terms of scenery and airports. I guess the "full blown" simulator due out later will be more full featured, WX, ATC, More planes, etc., like FSX was.
