[citation][nom]wildkitten[/nom]Your post seems to assume F2P games have no associated costs to them once you start playing. The sad fact is, that's really not true. Most F2P games are really P2W (pay to win), in other words you buy the goodies off the cash shop like weapons or armor that you can not get in game (or is ridiculously hard in game). The only game that has come close to F2P right is Guild Wars, which is more B2P (buy to play) but they are a rarity.And I don't know what you mean by infrastructure in place. There is as much infrastructure in place as there was when EQ started. Maybe more people have broadband obvioulsy, but each game has to set up it's own server farms for the game. Not to mention $15/mo for an MMO is hardly extravagant spending. People can spend that easily for a 2 hour movie (if not more). I peronally would rather pay a $15/mo sub fee for a game where I have the exact same content and features as everyone else playing. Most people spend more in the so called F2P games.[/citation]
Well, first of all, yes, they still need to set up servers to run the games today. But, there's a critical difference. The amount of data going through the network for any given player is more or less the same for WoW as it was when Everquest came out, the only differences in required computing power are taxing on the clients, not the servers. A modern desktop computer is far more powerful than an entire server was back then, let alone comparing a modern server to one that's fifteen years old. On top of that, significantly faster internet service is significantly cheaper now than it was fifteen years ago. These two things alone make it obvious that modern MMOs are basically just charging users because they can, rather than because they actually need the money. Sure, $100 a year isn't horribly expensive. But, compared to a $60 game, a $160(much more if you play for more than a year) game IS horribly expensive.
As for pay to win versus free to play, that's just a matter of implementation. Sure, there are a lot of examples of "pay to win" games out there, but the vast majority of them aren't even good games after you've paid for all of the locked content. It seems like, right now, most of the free to play games that aren't pay to win are also the free to play games that are actually good games, regardless of whether you put money into them or not.
