One area of much recent discussion among games developers, and players alike is how best to conduct a free-to-play model. Other than an issue of monetitization it is a huge issue of gameplay as fair play, an area of games explored by Consalvo (2009), is always comprimised by pay-to-win goods. In this article Shokrizade introduces the useful term of ‘supremacy goods’ as a way of identifying any game that straddles over the line into pay-to-win. Given the explosion in F2P games this is a space to watch.
