Developer Toylogic has just revealed that Happy Wars, the first microtransaction based Xbox Live Arcade game, has reached the two million player mark. To celebrate, more content updates have been added.
Although it may not seem like two million users for a free game isn't that big of a deal, those are still two million potential customers. Even if everyone only bought a starter pack, most free-to-play games would still be a profitable endeavor.
This particular game clearly benefits from the unique position of being the only free-to-play game on the 360. Hopefully we'll see more games follow suit on the 720 and the PS4, as options are always a great thing.
