Star Wars: The Old Republic

As any other MMO, Star Wars the Old Republic(SWTOR) encounters a bunch of flaws. Detectable but minor. SWTOR's endgame content is lacking, repetitive side quests and very long time between content updates.

But the storyline and general feel of the game-play and leveling mechanics. I've leveled up several characters just to level up. I do not think there is any other MMO that has made leveling up so much fun as it is in SWTOR. The storyline is one of the most magnificent mmo story lines and possibly the best mmo storyline ever created, for each class. Each class departs on different journeys, sided with either the Republic, or the "good guys" and the Empire, also known as the "bad guys". Each side has 4 classes each, but these are mirror classes which makes the sides balanced when it comes to the PVP part.

This is one of the most enjoyable games I've ever played.
