Already been said, but the parts I enjoyed most were:
The treasure hunt.
The story - I loved the news pieces and reading the codex entries. Was very immersive.
World PVP. We had some great scraps on Tatooine.
Cons:
1 new daily per day - I don't want to feel like I HAVE to play a game every day. Which I did because...
The event was a bit too short, maybe 2 weeks to allow for RL commitments.
Can't spend DNA samples now. We can still get DNA samples as the plague is still here, but can't spend them any more. I suggest a permanent vendor for time sensitive currencies like this.
