Despite the can of worms it can be,"from a business standpoint, subsidizing RMT is a fantastic move," Henning writes. If players will buy items and currency outside of the system anyway, what company wouldn't prefer that cash to enter their own pockets? "From a design standpoint, however, RMT is a treacherous path to walk," Henning cautions, and goes on to look at the pitfalls of game design that incorporates RMT. Conversely, the writer then discusses the level-disparity design problem in World of Warcraft and how it actually encourages players to buy gold and use power-leveling services. Henning also looks at how the ancillary services operating within and around a world pull in more revenue than the world operation itself, citing Raph Koster on the issue as well. Have a look at the piece at GameCyte, which discusses how RMT affects console gaming as well as MMOs, and just how inescapable it really is.
