It's rare for something that's free to come with no strings attached, and is actually fun to boot. An MMORPG called Runescape has decided to do just this.

I discovered Runescape on some banner on a website, and I figured that it was something to pass the time. I didn't actually think it would be that good, but I tried it out anyway. I was mistaken.

Runescape takes place in a fantasy world filled with goblins, undead, wizards, your typical stuff. The goal of the game (if there ever is one in an MMORPG) is to finish the quests that you are given, advance in your skills, and as always, become more powerful. This is done differently than normal, and since there the game is skill-based, not class-based, you can become proficient in all of them.
