It is indeed getting to the point one might raise questions or wonder about the future developments of this game. We have had assurances that something is being worked on, but the overall secrecy, and lack of interaction and communication doesn't do much to allay concerns.
The game has potential for future developments, but even without major additions it is a great game. It would be sad however if it ends here, as there are so much more within the universe that could be added, and certain aspects of the game that could be tweaked.
New content would be very welcome, be it another race, another mission type for more variation or even just the addition of more fleet variations or new abilities and upgrade functionalities.
