Your system is too easy. More like 1000 Glimmer to purchase 1 Spin metal, etc. This would give more use to the Glimmer and would provide an easy, yet still regulated, way to achieve upgradable material. If you need it right away though, you have to farm. Here is the effect of a good price point: -Picking up material won't be useless. -If you need it immediately, then you will still have to farm. -Extra use for Glimmer. A worthwhile one at that. -This also encourages people to use the consumables to make glimmer. -The price shouldn't be so absurd that people would just rather farming. -This also encourages play on all activities because you are guaranteed Glimmer. Glimmer doesn't get earned quick enough to ruin the game too. I am not saying 1000 Glimmer is correct but I am saying that a proper price point must be thought about. As for the other things, they are independent currency and I find no need to change they way they are earned. Black market isn't a bad idea. Just the fact no item will be unique; everyone will have everything. I have a large quantity of raids guns that would be on the market immediately, there are guns I still need. Guns go in streaks for some reason...
