I just installed it and played it for the first time - it rocks!
Very intuitive interface, fluidity, quick reaction time, stability... Well I can feel the change over my good old lagging Fleet Command, which wouldn't let me play more than half an hour before another CTD...
Really that's a great job. Anyone who played Harpoon and FC will not feel lost at all (didn't even check the manual for my first try) and, still, the qualitative and interface leap forward is huge. Can't wait to see accurate models for the plate-formes, engine sounds, ship wakes and all
