[citation][nom]lpedraja2002[/nom]Wow so many MMO's changing to free 2 play, I can't believe developers still haven't gotten the message. If your games sucks, no one will pay to play it for long! This game seems interesting I might check it out.[/citation]
What you don't understand is that most of these games were quite profitable without F2P, - but it has been demonstrated that the average person the uses a "free to play" account actually spends more month than a subscription player. And, adding the F2P brings in players that wouldn't otherwise play the game. These kinds of players tend not to stick around, but they spend more money when they are playing, on average. Adding F2P to a failing game might save it, but that's not why most publishers are doing it, they are doing it so that a game that is already profitable makes more.
So, the plan today is - release your MMOG with subscription-only terms, get the game paid for quickly through initial sales and steady payments, and then go F2P in order to rake in more cash for a game the subscription players paid for.
My recommendation is that any player looking to play a new MMOG simply wait 6 months; no point in buying the game if you don't have to, and some of the bugs will be worked out by then, too.
