Doesn't matter what featurs could be in demo... just ti give you possibility to test for one wekend start/save/load...
If it works fine for user - so much the better !
If it is c**p - lets make it straight and fair !
Otherwise, all these stories sound sleazy ...from such a giant and famous mouth called Ubisoft
(Just don't tell me that Ubi lacks resources to set up one demo mission... )
