The best part for your best decision to make on whether or not to become a full-time subscriber for the World of Warcraft game is its free trial. Because of the fact that World of Warcraft requires its players to pay for a monthly fee, a vast majority of people will definitely want to test the game to see how it is actually before paying or subscribing to it.
Therefore, World of Warcraft will offer people a free trial in which they can try to play the game for a short period of time. The WoW trial period will generally last for 10 days or more to make it long enough for people someone to experiment with the game and decide by themselves if it is really worth paying for it each month or not.
The trial also not has any limits (with the sole exception of the time restriction) and it is exactly like playing the full version of the game. After being satisfied with the overall game in most aspects, they finally will decide for the subscription to it.
