hm, i think its fiting to the startrek universe to have mining beams.. yust think of what has been done with the tractor beam during TNG

they can collect everything

I think its more fun to have variety.. well play the ciadan, they will have Dysons spheres arround moons to collect resources, or play the iconians, who dont have any resources at all..
okok, you cant play them in the current beta, I'm back to work now
