If your preferred sort of RuneScape is the older variety of schools, we’re sorry to inform you that the price is going up. On the bright side, you’ll be happy to know that it’s not going up to anything approaching unreasonable levels; the cost of a one-month subscription will be $10.99 for US subscribers, which is still a fair bit cheaper than the industry standard for subscription prices.
You know, to the extent that an industry standard exists any longer, what with everything having a free option these days.
The game last had a price hike in 2015, so it’s been relatively stable for some time (that was, to be fair, the “current” version of the game). On the bright side, you won’t have to worry about the price hike if you’re already subscribed; the changes only affect new players and those who have been unsubscribed for at least 14 days. The FAQ clarifies this along with explaining some of the world economic factors like Brexit that have spurred the change, so at least it doesn’t come without warning.
