I got into the beta for this game, back when it was being run by Monolith. A few months after release it was bought by Sony Online Entertainment and recieved no where near the publicity that Star Wars Galaxies or Everquest 2 gets.
Over the last 3 years the game has changed dramatically and improved. While it dosnt have the population of some larger games or the most regular content. It boasts, the best comunity ive ever seen in a game and regular live events (1-2 a week per server) involving characters from the movies. These events are the barebones of what makes this game great.
Another great feature is the ability to change class at any time. If you know the movies you know how they learn their skills. Its as simple in The Matrix Online. One minute you can be a master of Kung-Fu, the next an expert Sniper.
The final unique feature of the game is the combat system. The "Interlock" system brings combat in a series of animations, locking two combatants together. This gives combat movie like flowing action.
All in all a great game. Well worth buying.....
