Just came here to say how much I loved the whole Nimbus story arch of the Romulan missions.
I've never really had a problem with the traditional space-ground-space episodic formula of past missions, but I must admit the Nimbus arch adds a really refreshing change.
It feels like a dynamic world. I get the feeling Cryptic have learnt a few tricks from Neverwinter, here. The random world events and the fact that the planet isn't a private instance, just makes it feel that much more alive.
Playing those missions is the best fun I've had in STO for a long while. This was only enhanced by the fact that I'd only just watched ST V last night.
Well done Cryptic
