I'm currently playing Monster Galaxy, if you were a gamer on Facebook in the early 2011 era, you might know this game, a nostalgic game that was re-developed by Gaia Online. And if you want to profit from this game, I don't recommend it, AFAIK the people who play this game are super fans and just want to reminisce. But even so, that doesn't mean you can't get $GGM from this game, you can also sell it on several exchanges.
