In my oppinion, you don't have to strictly follow cannon. Even SAO has crossovers like Versus and Alternative GGO. You can compare that to Batman vs. Superman and other superhero showdowns. I have nothing against that though I think that DC and Marvel went a bit overboard. However, it makes no sence to change original story. You can extend it, you can make other arcs, stories, movies... If you want to change original story why would you write it in first place. Changing story makes no sence to me. That is the reason why I don't like game adaptations of SAO.
