One of the UK’s home-grown video games is turning 25-years-old, and anybody who ever had to sit through a boring IT lesson at school likely already knows what it is. It’s RuneScape, the point-and-click MMORPG that not only has remained popular over the years, but has seen a surprising amount of growth recently. The big question is: why?
