@StarWind27 Pariah is right, terrible idea. Especially seeing as doing the weekly challenges on average nets you 500k+ Meseta, and most active players consistently have that. You need the money to go somewhere to drain inflation, not take away the players right to set their own prices, and not inject more money into a problem where having too much money already in market is the problem. You obviously don't understand how transactional markets work, the real issue isn't in initial sales, but with scalpers that buy items that players put up for more reasonable prices, and then resell after they have the monopoly of the product. You combine that with a drop in players due to lack of story, or loop content with replay values, and you have a low supply, in high demand issue, where the scalpers that have the monoply on what little there already is, set the prices.
Just look at console shortages, and how Xbox/PlayStation consoles where hard to get, and are likely still hard to get, because scalpers buy up the stock at the flat rates set by the distributor, and then resold on eBay for upwards of a thousand dollars or more. You need to apply real world economics to the in game player market to understand how to fix the issue, and your solution is not the fix.
