Knight Online

Free! A Free game! I think the fact that this bit is called Freeware and it's stuck here in the Freeplay section somewhat dampens the impact the word free' actually has. So let's repeat it one more time - free! You don't hand over any money, and you're being given a full 3D MMORPG with knights and orcs, battling and levelling up and all sorts of looting and MMO Gerrific (it's a word) fantasticisms (that's not a word).

It has neither the user-friendliness of World of Warcraft, nor the technological superiority of EverQuest II, but it excels with a huge array of items, weapons and armour, all of which are upgradeable if you possess the right scrolls. The entire world revolves around the concept of a war between orcs and humans, so PvP is most definitely in, with universal scorekeeping and base-capturing gameplay abound.

Of course, it doesn't have the depth of the more popular bastions of MMORPGing, but (we may be repeating ourselves here) it's free, and definitely worth a shot if you fear opening your wallet.
