I've written quite a bit about Caesar here over the years. You may be interested in this about whether Caesar had some kind of plan for the civil war, and this about whether he was the first emperor (he wasn't at the time, and we don't count him that way, but some medieval types did), and this about whether Caesar was a tyrant, and this about a meme that started spreading scandalous stories about Caesar.

But someone asked almost exactly the same question as you about three months ago. While there are always, ALWAYS more opinions about Caesar others can contribute, you might find reading this interesting while you wait. I argue, whether deserved or not, Caesar's reputation is largely due to the good press he got from Augustus.

You know, after looking over all those old posts, I might as well try to write a fuckin biography of the guy. Book idea #3 that most likely will never happen.
