I'm familiar with the broad outline of Napoleon's career, from his campaigns during the Republican Era to the Battle of the Nile, to the Consulate, to the foundation of the Napoleonic Empire.
From what I gather his greatest innovation was highly mobile artillery, though I don't quite grasp the implications of what that would have meant in 1800. Other than that, I'd be hard-pressed to explain anything about his success or career.
Is it accurate to call Napoleon one of history's great generals, and if so, how come?

While there is always room for new answers, and engagement by whoever answers, there are potential answers in the /r/AskHistorians FAQ, especially the Napoleonic Wars subsection
On Napoleon's tactical prowess, by /u/DonaldFDraper; that would be a significant starting point.
Since this would likely be answerable for someone who could answer this. What was special about Napoleon's abilities (from the norm that wasn't almost dominating all of Europe)? Was Napoleon good at anything other than generalship, like say art or economics?
