Okey so I really love the workshop, however I see a problem with what I understand of the current workshop idea. As I understand it any player created content that will be added to the game will be available free of charge. I understand the idea of this but do not fully approve it.
For now it might work but in the future the player created content may be so large that the GOI content that can be bought with money will be left alone. Instead of giving the content for free a better use would be to sell it in the shop. If a player created content is bought you can give a part of it as GOI currency or something simmilar to that player.
The reason why I think this is better is because it will give more money to GOI and ensure the good future of GOI.
I understand that this may or may not have been suggested earlier and it might even be under construction as of now but I wanted to say it anyway since I really love the game.
