1. Dogfights. I love pulling crazy manuevers around an Arcadia or Orion, especially aircraft-style manuevers, like when you pull up on the joy, twist left or right, and level out on either side of your wingman.
2. FRED. Easy to use, very flexible, and you can make campaigns to get all medals and promotions.
3. Beamz. Beams help me with dogifight manuevers and they're just plain awesome. They really give life to capship and capship to fighter battles. not like FS1 where the bombers do all the work.
4. Surprises. Everything is not as you expect them to be (well, when you first play it anyway
). The Lion's Den had surprises (you know what i'm talking about)
5. Awe-inspiring ships. The thing that makes ships awe-inspiring are their entrances. The colossus jumping in to save the day, the psamtik doing the same, the sathanas jumping in with all guns blasting. it's just awesome.
