Bitcoin subscription for games back in 2009-2011

I remember getting bitcoin for subscription time for games back in the early 2000s. Gunz Online, City of Heroes, or Rose Online? Something like that. Not quite sure. Hope it's ok if I ask this question here. Trying to see who the company was that facilitated it at the time.
You would get like 5-10 for $20-30 of game time.

Thanks in advance!
