well ill have to agree with poster above me it would be boreing
what you have to do is add like a tournament or somethign where other players can fight for minerals to help upgrade
-good system of battaling
have fun missions and maby diffrent "jobs" like in some of the Final Fantasys there was a job system where you could change what type of person you are liek white mage and such (but thats not what your looking for)
you need to like have a good job system and diffrent jobs you can change after your done with that job (confusing

)
