Kinda looks to me that the only line you read of hewhoispale's comment was the one you quoted. As he says, we have seen most of the games features in multiple WWWs, including the multiplayer WWWs.
Where was the naval invasion? Sorry I just don't think that landing 2 divisions in China with zero resistance is showing us how the naval invasions work. That is just my opinion. So we could not witness the D-Day invasion? Because someone would have had to play the game behind the scenes get very close to D-Day then start streaming?
Big changes with the Battle Plan system. Seen any information on that?
Wait fighters don't what? Bombers mystically transport where? AA guns actually work now? But we can't see any of that in action?
Now if they at least showed Germany then hey we would have been able to witness everything but a huge naval invasion? For whatever reason Germany was off the table.
So then why not choose to show the largest consumer market in the world how their country did it back in the day? We would only get to witness each and every change and new system that HOI4 uses. Hey, maybe even have an question or two answered in the chat room! Imagine that! Hey America make sure ya'll shell out that $90 for a shit ton of features we promise are there but are not willing to show you.
Well I've explained my side as much as I care to. As you can tell from my previous posts I am one of the largest fanboy's here. It is just sad I can't see the new features that are to be so great but I get to keep watching pre WWI hand gun shoot outs.
