Yes there is. Runescape, Aion, Guild Wars are just a few of the many games that are along the lines of World of Warcraft.
Guild Wars, which was made from ex-Blizzard employees who worked on the original World of Warcraft, has no subscription fees but optional in game item purchases but those aren't required. The URL to find NCsoft's games is linked below. Some are pay to play but again, Guild Wars is not.
Same goes with any of the games by Perfect World Entertainment like Perfect World International and Battle of the Immortals. Perfect World is linked below also.
You can't. World of Warcraft requires a monthly payment. There is no way around this.
There is no way as of right now in that you can play Warcraft 1 for free.
The only way to playt World of Warcraft for free (legally) is to use a free trial account. This type of account is severly limited in the levels you can accesss and the chat channels that you can use.
You can sign up for a trial account, which will give you 10 days to play for free. Other than that, there is no way to play WoW free.
No, the trial account is the only way to play the official live servers for free.
There is no way to play world of warcraft free forever unless you want to hack blizzard itself which I do not recommend, or get on a private server that doesn't charge you. You can get a free 10 day trial forever but it's not worth it at all.
There is no legal way to get "free" authentication keys for World of Warcraft. You must purchase the discs or use the blizzard store to purchase one.
Yes. World of Warcraft is a MMORPG (Massive Multiplayer Online Role Play Game) game. Which makes it only online play.
If one is interested in trying out the MMORPG World of Warcraft, then a free trial is probably the best way to get started. The recommended method of doing this is to go directly to the WoW website and download the World of Warcraft Starter Edition.
No, you do not get free play time if you cancel your subscription. The only way to get free play time is when you purchase an upgrade. It will usually have a free month. You can also get free playtime if you recruit-a-friend.
No there is not a single player version of World of Warcraft. WoW is a MMORPG, Massive Multiplayer Online Role Playing Game.
The game installer can be downloaded freely from the world of warcraft website. You will still have to pay the monthly subscription fee. There is no way of getting around this.
