To all that plan to buy this game to play online. It might or might not be a good idea. I've never played the game online myself but I did play offline. I found the story to be rather interested. A couple of puzzles that literally took me quite a few hours to complete. The main game is actually quite good but what about after you complete the game? You can still play the game and because you are a higher level. Than you were when you first started the game. You can play through every one of the missions with higher level enemies. Or you can simply choose to play back through the select few you found interesting. The main story is short only holding around a thirty hour timespan for completion. After that the game grows somewhat stale and repetitive. The offline version only gives you the option of choosing a few classes. And the one you start out as can't be changed until you earn the right to select one of the others. Of coarse this process only takes a short time to achieve. Every class is well built and unique in one way or another. But I can't help thinking this game was cut in half offline. The people that put the game together could have offered more classes and features for the game offline that they did.
