You're asking for the equivalent of rebuilding a house by pulling out the foundation and replacing it and expecting people to be able to live in it at the same time.
The technical side is the problem. Would you rather they lie? If you think they're lying about the technical side do you think they're just lazy? How many people who work on this game do you think look at it and go.. "eh.. it's good enough. Milk it for money and let it die when people get sick of the lies".
