This is one of the worst Documented games I have ever played.
Even guides on this board are all but non existent; it seems the Developers have left that to 3rd Parties and players on YouTube.
Which seems very unprofessional to me. I highly suspect that just 1% of your Superbowl commercial budget would go a long way.
And this would encourage those players who respond to your ads to maybe stick around, spend some money in the gem-store.
I dont know get you a lll ROI. Just a thought. BB.
