I definitely think that free-to-play MMOs will be around for a very long time, Chilton said in a chat with NowGamer. At some point it's possible that World of Warcraft could end up being free-to-play, but I do think thereâs always room for there to be subscription games.. Chilton added that a monthly subscription can be a good value for some MMO's. A gamer could play WoW for dozens of hours in a month. When you consider the amount of time spent in-game, the $15 monthly subscription doesn't seem so unreasonable.
