I got the modded version of the game to try out the mechanics, found out these guys ripping people off, the more higher the level you go the faster you DO NOT go in mining and transporting. I maxed my miners to level 10,000, I still feel like I stuck in mining level 1, even if you used real currency, you will not see any change. Complete rip off... Now let's see how long can my review stay up. I'm gonna copy everything I wrote here and if they delete this review I'll post it again.
