That's true indeed, even the best game won't succeed without enough players to make it go off.
Obviously I'm a bit biased here so take it with a grain of salt, but I'm pretty confident that the game is going to take off at least within the crypto world. Last I checked there were already 320 unique accounts that bought at least an Origin - quite good for a game that only has an Early Alpha version to show and only relied on word of mouth for organic growth so far.
I fully trust its developer (@elindos) and he really is putting all his heart and soul into making the game. So while I can't make any guarantees of course, I believe that eXode will be here to stay.
