Even though I wasn't able to follow the story I could appreciate the effort put into it. The missions themselves are not overly difficult, and are not your standard 'fight off several waves of enemies' missions.
Awesome mission. A large scale battle between two groups, choices on the role you want to fly, no surprise failure objectives. A bit easy, but I prefer easy over artificially difficult.
This would be an overall excellent set of missions if it weren't for the few issues pointed out in previous reviews. Despite that it is definitely still worth playing.
Very straight forward missions. On the easy side but I prefer to feel like I am part of a battle instead of a 1 vs 100 scenario, so that's more of a plus for me.
