RuneScape's subscription fee is going up in 2015, but Jagex hasn't said exactly when or by how much. A posting on the fantasy title's official website pegs the timeframe as Q1 2015 and says that the hike will affect new members as well as members who have been unsubscribed for more than 14 days.
"If you're a member when the price rise happens, you'll see no change," Jagex explains. "You'll stay at your price as long as your active membership started before the date of the price rise. This applies for all previous grandfather rates, for those of you who've been subscribed for a long time. Should your membership end, you'll keep any lower price you're eligible for, as long as you resubscribe within 14 days. After that, though, you'll be moved to the new price."
