Knight Online is an MMORPG developed by MGame Corporation.
Knight Online's gameplay is similar to that of other MMORPGs; kill monsters, and level up your character. You can choose between four classes; Warrior, Mage, Rogue, and Preist. You can form parties with other players, which will cause you to level up faster, and you can set up a trade table where you can put up items for sale and wait for people to buy them.
You could leave your keyboard and come back two hours later and find that you've sold everything, or nothing. This MMORPG game could use a beginner tutorial, as it's quite hard to understand how to get to different areas, and what certain items are for. There are quests for you to complete, most of which require you to gather items dropped by monsters and return them to a NPC in town.
Eventually you can fight in large scale wars against other players. Your character has skills he/she can purchase with skill points to aid you in battle. The MMORPG game is pretty fun, if you can get into a server. Most of the time the servers are packed, and when you manage to get in, the towns can lag you due to the fact that there are so many people sitting around selling their items.
This MMORPG game is played on a global scale, and people of all nations gather in the servers. The only problem I had with this is that I could hardly find any people playing who actually spoke english. So, socializing could be a problem in this game. If you're looking for a free MMORPG with great graphics and fun gameplay, Knight Online is worth trying out.
