my take on this topic:
tldr. takes away innovative features that make Illuvium different and in many ways, better than currently existing games; only copying what others are doing rather obviously doesn't work, as we can see that usually the same few big IPs and Companies stay the same in Gaming.
To get players to change a game or try out something new, you have to offer something very different/better; same thing or slightly better doesn't cut it vs sunken cost of money/time in players' current games.
e.g. recent big hits:
Fornite-different Battle Royal, new mechanics like building etc.
Genshin Impact-Mix of high-quality JRPG Game+Gacha Game, targeted entire world, phone/pc/console same account
TFT-strategy game version of Battle Royal (+big IP behind it)
- Issues with Gameplay:
-The Idea is anti Innovative IBG concept
-Overworld and Zero are economy and trading-focused games, adjusting prices in a free market system is a positive and wanted feature.
The assumption "web2-gamers" won't understand or like this is rather baseless; many economy-based games in web2 with changing prices are big hits, e.g. WoW, Runescape, PoE, Steam-Marketplace etc.
People playing video games more often than not played some TCG in their life as well or are familiar with the concept of collecting irl-items that have changing prices on eBay or more specific trading platforms.
Taking free market Elements out seems anti gameplay and will make it harder for Overworld/Zero as standalone games and force them more towards "only a pack opening."
-free market economy on fuel makes playing the marketplace itself more enjoyable, which to many is the game they want to play (playing auction house in WoW/Runescape/etc.) and buying/selling assets based on small changes in fuel prices could have been their gameplay
- Issues with the Ownership advantage of web3:
-hindsight change on how land fundamentally works after people used $72mil to buy those based on a Thesis with weak arguments/more Thesis as arguments
->potentially alienate currently invested people and people who were fans of Illuvium due to innovative economy-model
-you won't start at the perfect price, and adjusting later causes problems as then people pay more or less for the same assets
-> This leads to "min and max prices" for illuvials, potentially making the entry barrier for Arena/future games too high or too low
-more potential botting problems, as fixed prices make botting almost guaranteed to be profitable, giving 2nd-market prices are high enough, compared to having to worry about fuel prices declining before you could sell, which would then reduce the asset prices as well
-free market likely would allow for people to convert time->$ a lot easier (playing the marketplace, reading charts, analyzing, etc.), which is still a baseline idea in ownership-based games aka transferring $ from whale with lots of $ and little time to someone with lots of time but few $
