IIRC, Second Life allows for players to sell the virtual currency to each other using 3rd party means, and players can also purchase the currency from the company itself.
So, based on that, any players willing to accept Bitcoin in trade would technically count as the game "using" Bitcoin.
And since the devs claim that they don't own most of the content within the game, they can claim that there is [thing] within the game, without having to do anything themselves, if I am correct.
True! They really allow for the users to do their own business, and they were indeed an open source software which meant that users could even develop in game apps.
However, I heard they closed their source code and now only work with some specific meshes of developers. And they do demand that the users use their inworld currency - Linden Dollars. but of course that aside the game, there's nothing saying that users can't deal with other currencies if it's that what you mean...
The Question is, Has Linden ever commented about bitcoin?
