Meleagar's article reads like a (decent) fan-zine, not a pro-zine (professional magazine, if "pro-zine" is unfamiliar.) It also raises valid points, many of which have been discussed here. As a player I'm willing to do a certain, limited amount of "grinding." As a player I like the Free to Play (F2P) model as an extended trial to see whether I like the product enough to subscribe. One of my friends is an MMO player of considerable experience (she now gets paid to develop wikis so has to play even games she doesn't like) whose initial raves over GW2 soured in about two weeks, for the reasons Meleagar writing about (cash shops/pay-to-win) and others. Meleagar also seems in favor of a Consumer/Player Bill of Rights (another topic we've discussed on these forums.)
Myself, I'm happy to pay $15-25/month for an MMORPG subscription. For myself, it's good entertainment value for the dollar compared to movie house prices or even NetFlix DVD rentals. I already know from LOTRO that I'm better off subscribing if I'm going to play beyond casual low level, because it will cost me much more as "premium"/silver than as a subscribing VIP/gold player. Meleagar raises some interesting issues, and I wonder how long it will be before Industrial Engineers, Psychologists and others are brought in to figure out the best most cost-efficient way of fleecing the players. Maybe they're already here.
If Meleagar's prediction about online MMORPGaming is correct, then it's likely I'll switch back to stand alone computer games, such as Civilization. Barring that, I'll break out a deck of cards and gather some friends. If my hand warrants it, I'll start the bidding at One No Trump.
