Runescape sets a record

Guinness World Book of Records officially recognizes Runescape as the largest free MMO and the second largest MMO. There are about a million paying members and about five million free account users and since Runescape those not separate players per server it is possible though not plausible to meet them all.
Many changes were applied since I started playing but IMO these changes are for the best in order to avoid an imbalance game economy and discourage cheater though the said same changes have eliminated some of the features that I hated and loved (hated: PVP ambushes, loved: pricing way too low or high).
Runescape does not require the latest CPU or is not a memory hog but having a good PC does help in game play and factor in a fast internet connection however these are not necessary unless you are an ultracompetitive player.
This is not a game for eye candy or jump-whilst-I-chop-your-head-with-a-twisting-slash lovers but this is for people who likes to plan ahead and live in a semi real world.
