This might have been suggested before so pardon my unoriginality if so.. but I'm going to expound on it and try to actually get it passed...
So this would be a place where you go to sell and buy whatever you want bought and sold by the players.. you set your sc prices of what you'll sell whatever item you want and people can buy it for sc or reds...
this would be super amazing for players and for super mechs because..
supermechs could imply a tax on both the buyer and the seller
I was thinking a 10% tax on the seller then a 10% tax on the buyer.. thus they split the tax but super mechs gets a 20% tax on everything that is sold.. but it could work differently.. they make money we get items cheaper and are happy.. also for buying and selling things for reds.. they could charge a 5k sc fee from the buyer and seller each of those transactions or something similar (idk reds are more valuable)
This would make the game explode.. like go crazy with awesomeness.. but I"ll let you vote on it
