Why shouldn't there be an end game? It's not about winning anything, it's about doing something that actually matters if you've played long enough. Like every MMO, be it some huge PVP stuff or something else. You can't do anything different, doesn't matter if you've played for 10 hours or 1000 hours. There should be something different at some point in your career.
And no star naming please. Human mind works so that stars are named either as something phallic or offensive.
