Conquer Online is a great game, and it is relative easy to play. Here is a general introduction about the game. I know it looks hard but it is really easy.
If you decide to play CO, here is what you have to do:

1. Your first character should be an archer, because:
It is easy to level up, thanks to a spell named Scatter that can hit all available targets around you.
It is perfect for gaining money and buying good gears.

2. After you gained enough money with your archer you can make another character. Your character can become Reborn after it reaches level 120 (or 110 for water taoists). There are lots of combinations you can choose from, all having advantages or disadvantages.

3. Do all the Bonus Equipment Quests!!!! They give you very powerful gears without spending any money. If you will have free gears other players will call you a noob (newbie). Don't mind them. They are jealous on you because a noob can kill them.

4. Join a good guild. There are wars between guilds every weekend. The GuildWar is important, because if you and your guild win, the leader will probably share the prize with the entire guild. It is important to be in a guild because when you get PKed your guild members will help you incumbently.

5. Make friends. Friends can help you when you need to be helped and they can share to you some tips.

6. If you enjoy the game, you can buy CPs from here because they will help you to get good gears and you will be more powerful.

The game has a PVP option, this if you want to kill and to be killed. There is a Class PK War every day. There you can fight against players with the same class like you. If you win you will get a good exp reward and you will be more respected.

Soon in the game will be added horses, so you will travel lots faster.
