RuneScape is a Java-based massively multiplayer 3D adventure, with
monsters to kill, quests to complete, and treasure to win. You control
your own character who will improve and become more powerful the more
you play. The game boasts more than 300,000 concurrently playing
players. It is a game that more or less tests your patience. It is by far the best free online game available. You can, if you choose, become a member for 5-10$ a month (Depending on which payment option you use). There are many benefits to becoming a member such as use of forums, polls, weapons, quests, armor, and areas to explore.
