To my understanding, VoidSpace is being developed as a testing platform for the core features of the Universe Project itself. As UP necessitates a rather complex architecture and communications framework, VoidSpace has the capacity to serve as an effective testing ground.
Not only this, but it will also show how easy (or, as the case may be, difficult) it is to write good game logic with the existing framework, so that it may be tested and refined for both ease of debugging and internal efficiency before being released in the Universe Project itself.
To my understanding, the ultimate goal of the Universe Project has not been lost, but has been somewhat deferred during the testing of individual components and, as you see in VoidSpace, the merging and synergy of those components in practice.
In other words, patience, padawan. All shall come soon.
