Mixed bag. First, there's a large number of primarily Korean MMOs that use the FtP system, and its clear that there design choices were based around sucking up money, not making the ame worth playing. Those are not good. A lot of MMOs these days, like Star Trek, are low quality games, and FtP makes them worth giving a shot, not to mention give the developers a little money. There still not very good games, but the FtP is a good aspect of them. Lastly, there is not so much a category as a single game: DDO. DDO is what all FtP games should aspire to be. It is a complete, enjoyable game that offers actual content (Instead of purely aestetic options) for an additional cost, without granting an unfair advantage to people with deep pockets. A Drow Favored Soul (Which would require purchasing Drow race and Favored Soul class) is not necessarily more powerful then a human Cleric, but it is different enough that the cost actually gives you something interesting to do, without marginalizing the Human Cleric player. And also, simply playing the game will grant you some points that you would normally have to buy, giving an even greater sense of accomplishment. On average, subscriptions are better for a serious player, FtP better for the casual player who can exhibit self control, but FtP has the potential to be a superior system.
