Well I for one tried Discovery just to see what it was like, and after spending about a day or two there for the sake of giving it a fair shot, I quickly realized that imo Discover sucked. It lacked EVERYTHING that I love about Crossfire. The community there was horrible, everybody expected something in return for even the smallest bit of help. The graphics were about as vanilla as it could get and therefor sucked. And the amount of systems, quests, and overall extended storylines it had was very very lacking with no real endgame goal, something Crossfire excels at. Even the station building feature it has sucks because its very much not worth all the effort it takes to make and maintain one.
I would like to quickly say that I am not posting this for the sake of dissing on Discovery or anything, this is just my own opinion on something new that I felt like trying out. Other people may or may not think the same thing as me.
