I just finished playing the Devidan series, and I think it was ten times better than the Breen series. I loved going back to the 23rd century and meeting Scotty and Bones! That was incredible! The special reward was really good as well. Oh, and I loved finally getting to slingshot around the sun! I've wanted to do that since the game launched! I can't wait to see what is in store for the next weekly series!
P.S. Does anyone know when the next series starts?
