My proposal for a potential new idea is to allow us to buy/sell fuel on the marketplace. The pros would be that players who don't use all their fuel and need more income could sell theirs, and players who want more fuel could buy obviously. The cons would be it could potentially disrupt some of the balance in the game where fuel prevents whale players from taking all the SH/BH medals.
There would need to be consideration on if the fuel still resets each week as this would cause the market to be wiped out as well but the price per fuel would also probably drop as we get later into the week. I think that would be fine, just something to be aware of.
Additionally, there could be a bigger update where fuel now becomes a new resource that can be extracted/refined just like food/weapons. This would be a new industry for companies that would allow us one more thing to produce.
