Azeroth is a world whose lengthy and tumultuous history is forged in the fires of unremitting conflict. It has been four years since Chaos reigned over this scarred world and King Arthas of Lordaeron was driven mad by haunting visions of the Frozen Thrown of Icecrown. As was inevitable, history now repeats itself as armies of the Horde and the Alliance prove their mettle on battlegrounds and clash weapons and magic in colossal, organized territorial raids. Your time has come. Choose a side, sharpen your skills, and make your mark on Azeroth history.

World of Warcraft is the first MMOG in the (so far) four part Warcraft series, with previous Warcraft titles being RTS games. Like most MMOs, players may find adventure in fighting various monsters and in performing missions offered by numerous NPCs throughout Azeroth. In World of Warcraft, success in these endeavors yields rewards in the form of currency, items and experience. Players may also take part in PvP battles in the forms of dueling and fights with players of opposing factions. In the early to middle stages of exploration around Azeroth, most monsters and quests can be handled solo. Past that point, however, more and more gameplay will require a good team of players, usually two to five in number. Large-scale raids can require up to 40 players to succeed.

There are no classes or levels in Wurm Online; instead the game focuses on skills that the person chooses to advance. As skills are trained, they become harder to train, since a master has little room for improvement. One will also find very few NPCs - the world is very player driven.

The world in Wurm is dynamic - resources must be discovered and are renewable. If you cut a tree, it will eventually grow back. Crafting with these resources is also an extremely deep system as it takes at least several detailed steps to create new items. Essentially,Wurm is a real life simulation of a rural resident in a simple time and place. The game requires a subscription, but at least two months' time must be purchased for 10 euros (around $15) at a time.
