i'm ok for a market in game for the peoples who like to créate some clothes, i know there are.
but we already pay the game, some peoples pay by year, some by month, 20 euros i think, with this i can have new games all months on steam.
there are market often when it's a free to play.
I play sometimes a game on ps4, nebulla realms, it's a social game released in 2016, it's less beautiful than 3dx but there are 100x more clothes, lots of activities (bowling, billiards, karts race, shooting bow ......), lots of dances, clubs, beach, a room editor, some updates every month often...... and the game is FREE, just a market.
i think the dev of 3dx can do lot more really.
