Can’t do it in ESO. You can’t buy a token to sell for gold. So, that’s just wrong what you said.
Same for SWTOR. I’m not sure but I don’t think you can for FF14.
Closest you have was Wildstar but you couldn’t carry in that game due to a lot of damage checks.
Maybe Eve? It allows you to buy something to sell for ingame currency doesn’t it?
So no, not every game allows it….
