Sarcastic, genuine, or merely self-promoting? An open letter from GamersFirst's Joshua Hong to Activision-Blizzard's Bobby Kotick following World of Warcraft's surprise move to an indefinite free trial could be all three. "I wanted to congratulate you on taking your first big step to join the Free2Play® revolution," Hong writes.

He certainly isn't shy in expressing what he sees as GamersFirst's great accomplishments in the market: "Having created this market in the western hemisphere, it's very encouraging for us to see the last bastion of the subscription-only online gaming business joining the Free2Play movement... Given our recent success in reviving APB Reloaded, which launched as a subscription-based game we transitioned to Free2Play, we know that the first steps are often the hardest. But the proof is in the metrics, as APB now has more than three times the active player base than when it initially launched as a subscription product. We also plan to repeat this success with Fallen Earth."

Hong continues the letter by "extending [his] friendship and support" to Blizzard, inviting Kotick to the free-to-play party at Gamescom, and hoping that the company's entire library will be made free in the future.
