This highlights to me perhaps an unexpected impact of the F2P / Freemium conversion process – it may actually be removing players from subscription-based titles. There will be those who don’t have time to play several games so pick the free one for their limited time, or perhaps feel that the value they get from one game for free is worth more than the value they get from another title at $15 a month.
As such, the only way to keep those players is to offer a F2P / Freemium option as well.
It really is the end of the subscription model’s glory days. Hope you are paying attention, EA / BioWare.
