There does seem to be a recent trend for F2P games to make changes that scale back the free content to regain profitability, and I predict a massive backlash from the player bases of those games. We are seeing the backlash already. Players have a very low tolerance level when it comes to the kind of changes that end up costing them more $$ especially with the incredible high number of games active on the scene right now. I know most players concentrate on just a small number of games at any one time so they may be unaware of how crowded the market is right now, but it is huge. There are tons of really good games - many of them F2P - and the player is kind of forced into being wise with their gaming budget both monetarily and timewise. There is only so much time in a day to devote to gaming and players want to invest that in a game or two or three that is worthy of their effort. It's understandable that these MMOs want to attract a large playerbase, but when they change things up or trick the players into a sub then they are going about things the wrong way.

The F2P's as well as the Subscription games should err on the side of giving away too much content instead of the current trend of scaling it back, or what they will see if their players start leaving en mass, leaving them with zero dollars instead of what they currently have. It is a fine line indeed, but I really think the key is to make more things accessable to the free/casual players - not less.
