Hello,
I'm new to Sins, I wasn't in the beta and just purchased the download copy the other day. One thing that irritates me a bit is being forced into Metal Mining or Crystal Mining based on the Asteroids surrounding a planet.
Early game it can be quite frustrating having to go to the black market to buy crystals for almost anything you want to do.
While I see merit in Asteroids that are only suitable for one type of mining, I think it would give the player more strategic choice if there were "Hybrid" asteroids where you could mine for crystal OR metal, your choice as a player.
