Some of the MEs retcon important information, though.

Spoiler for Vol 1 + ME2/ME7 spoilers:

When Kirito uses a hand-to-hand sword skill to finish of Cradil, it makes sense due to the events of the Aria continuation ME which showed how he got the skill from interacting with Argo after the defeat of the first floor boss.

On the other hand, ME2 which shows Kirito's (and several others) level and skills upon the game being cleared, clearly lacks the hand-to-hand skill. The only skill we are aware that he dropped during the story was 2H swords to pick up fishing, so ME2 actually created another continuity error...

There might be more, but that's the only one I can think of atm.
