To be honest I have a hard time understanding why anyone likes this game, it is a nonsensical mix-match.
As we all know this game started out as a multiplayer only game, then it changed to single player mid stream. Before any of you say that these things happen when developing games, the short answer is --- no, they don't.
A good anaolgy would be if you were making a building. You make the blueprints, buy the materials, hire the construction workers, and start construction of a 100 story skyscraper. Wellright after the first floor is laid the owner calls up and says, "You know what, we want a cathedral instead, but be efficient about it, I don't want to lose any work already done."
So they lay off the wrokers for a while and draw up new blueprints for a cathedral. But the first floor has already been built, so in order not to lose anything they incorporate that into the new blueprints and carry on from there. So the first floor of cathedral was supposed to be a skyscraper, they just repurposed it.
If you think that sound like very poor planning to the point of being ludicrous, it is. But that is exactly what they did, they had the infrastrucutre or "first floor" of a multiplayer game done, then repurposed it for a single player game. No one in the industry changes games that radically part way through because it would be a disaster, just like the cathedral would be.
They might say, remove features or change features part way through. But that would be the equivalent of making a room bigger or making a room into a bathroom so now you have to run pipes trhough there. They would certainly not shift the entire focus of the game to the point where it is now a completely different game. Just like you wouldn't change a construction job part way through to the point it is a competely different building.
The end result is a mess, and is one any developer should be ashamed of. To be honest, I would have to imagine that any big-wig that ordered such a move had no idea what it was he was asking because if he did, he would know the mess it would create and not do it.
Anyways, if you enjoy the game, good for you. But to me it is just a bunch of concepts and ideas thrown together half-hazardly into one big chaotic mess. Does it have its' plus sides? Certainly there are moments that shine because some ideas were good ones, and I guess I can understand that you might think that those great moments make the rest of the game tolerable. But the package as whole is still a mess in my opinion. Just like that cathedral would be.
