Just try it and see for yourself. The best server to choose is one called Helbreath Nemesis.
It has a great community spirit, forum, the best GMs (game master's - the people who run it). And best of all, it's 100% free, and will always be so.
Just try it.

The Helbreath online game is fiercely competitive. It involves developing your character as a Mage or Warrior, or maybe as a Battle Mage by killing monsters and gaining experience points. This is no game for the faint hearted, because in addition to monsters, one has to beware of players from the opposing town also trying to kill you, thus they gain points and prestige. Within the game one can trade, buy and sell items, with rarer items being much in demand.
For those that have played that excellent game 'RUNESCAPE' and want a more advanced game, then this is definitely the one to play. Helbreath's graphics are way ahead of 'RUNESCAPE', and the gameplay, whilst more complex, should present no problems for RPG fans.
There are usually Gamemasters online; these are experienced players given special powers by the owners of the game. They are sort of in-game Policemen/Advisors, and are generally there to assist all players. It is hard to write a review without giving too much away. Part of the fun of playing is the learning as you go. One thing to always remember is to never ever allow anyone access to your account under any circumstances, this is a sure way of having the items you have fought so hard for, being stolen. Go try it, take the 14 day free trial, by which time you will be able to hold your own against lesser monsters. After that it costs $9.95 per month for unlimited access, you will require a credit card to play. Perseverance! When you first play do not be disheartened, as the gameplay will soon make sense to you.
