It's partially due to the frequent changes from a "Project Manager" who acts like a chipmunk on crack who also has ADD. Additional problems arise from an ever expanding scope, an engine that in no way was meant to support this game , and that the level of detail, scope, numbers of players simply cannot be supported by the (for lack of a better more correct terminology) proper infastructure. The Internet and these servers cannot handle this many details on this scale, with a grid size this large, with the promised number of players, missions, NPCs, items flying through space, particles blown off ships. missiles flying through the air, orbits to maintain. It's not feasable and will never be as long as they keep trying to make do with the current architechture and dont scale down their ambitions.
The fact that they have an out of date unemployable buffoon from several decades ago running a project that he is grossly unprepared for lacking both the skillset for managing people, or current game creation, nor the self contol to say"enough is enough, we are going with this" is a recipie for disaster.
I'm sure that the SC backers will keep tossing money into the dumpster fire for years to come and will wind up with some half baked piece of crap, that is if CR doesnt toss in the towel first from a lack of funds while employing 1000 people to keep up with all his whims and scope changes. Certainly it will be a crapfest no matter what.
We will need a deadpool to bet on how many whales jump off buildings. I hear you can bet on almost anything in Vegas.
