While they share the same name, the newer RuneScape 3 and Old School RuneScape are now quite different. The newer version boasts complex combat, better graphics, better boss battles, and is focused on PVE. In contrast, Old School RuneScape has simpler combat, is easier to run even on weaker computers, and is better for those who like some PVP action. That’s not to say one is inherently better than the other, but new players would prefer RuneScape 3, while veteran players will like Old School RuneScape more. The latter tend to be very nostalgic for its player base.
