No idea why it took me so long, maybe I was just to focused on training and online flights, but I finally managed to get my focus together and deal with the first official scripted campaign.
Here is some critique. It's not to say it's bad by any means, or that it's not immersive. It is and so much more. But... It could be better.
I liked the story in the briefings, but at some point I stopped caring to read them with attention. Maybe if there was some kind of intro, like in the old generated campaign focusing on the protagonist - the pilot. After all we are this particular dude, I'd like to see him, know his thoughts, what he hopes for, what he fears. The text in the briefings is sort of just there. Well written, but lacks something that would invoke personal engagement.
An additional thought here, is that the campaign would benefit from some cutscenes - an intro video or maybe comic strip narration like in CFS2 (loved those). For some reason I believe still images with text am music suit serious games... Nobody seems to care though.
As for the missions, they are not particularly challenging, but do require some flying competence, though they do make for a good introduction to the sim - most of the time weather conditions are far from good and you are supposed to stick to certain flight parameters. I like this a lot. It makes for some beautiful scenery.
Now that said, it starts slow and... does not ramp up at all. Somewhere in the middle there are some more combat-intense flights, but the last 2-3 missions are simple cake walks. Maybe it's my cinematic sentiment, maybe just some sort of routine from other games, but I would expect that the scale and difficulty would increase throughout the campaign and culminate with an epic battle. Meanwhile, the last mission is an escort and a cakewalk. Maybe a missed something, but it was a bit disappointing to do the full run without enemy contacts.
Now that said, I enjoyed the hell out of the campaign, and all the issues above aren't really that big of a deal, but... it's a scripted campaign and maybe due to some film / gaming habbits, one would expect something more dramatic. I really don't know how to say this, it was great, but maybe I am just not pleased with the lack of an epic final battle. Probably gaming habits - you expect an epic boss fight and a cinematic outro. All I got was a screen saying I did 15 sorties, got 11 kills and destroyed 2 ground targets. It's not really a complaint, more of a recommendation for future releases.
Anyway, it was a good run, hopefully it will get better.
