"Gamers have strong opinions when it comes to business models and monetisation in MMO games," said Jeremy Gaffney, executive producer at Carbine Studios. ”In combining a classic subscription model with C.R.E.D.D. we think we’ve struck a good balance."
"We definitely want to support players who appreciate the value of high-quality subscription-style game. Meanwhile, C.R.E.D.D. gives gamers who don’t like monthly subs the option to just play to pay and enjoy the same content."
WildStar will be at this week's Gamescom 2013 in Cologne, Germany, as well as at PAX Prime in Seattle.
