I don't understand your angle here. Instead of buying a game on steam, you buy a token. You convert e.g. a stablecoin to the game token and you can trade that token on the 2nd hand market later.
>Another aspect is that when the central authority is also the sole issuer of tokens, no counteracting forces exist to drive a meaningful market dynamic.No matter how much price pressure exists from users, the authority can always act to restrict issuance or increase issuance to force a particular price, and over the long term in the absence of that authority (due to bankruptcy, obsolescence, ..) the value of all issued tokens drifts towards zero.
That depends on the monetary policy for the token which might not be possible to change later on( at least in some blockchains it is set in stone for trust reasons). So you can't just arbitrarily print more or less unless you set it up in such a way in the first place which is transparent. Also I don't understand how the value of tokens drifts towards zero since they live IN THE BLOCKCHAIN and the smart contracts are working regardless of the gamedev existing or not. So you have a digital second hand market essentially.
