Ah, sorry I didn't elaborate, I was so eager to defend the Big N! Besides, I've had that argument so many times with my Sony fanboy friends that it's gone stale.
Anyhoo, about the map...you will probably need to get a whole new image, rather than inverting the colors and flipping it. Maybe you could do some kind of water reflection thing. Or, have one side embossed in and the other embossed out.
The general unoriginality of this map might bother some people, (like me), but you can't please everyone. I suggest you add some sort of gimmick. Perhaps you could do something like this: Make everyone start on one side, and fill the other with neutrals. Give the neutral side the classic bonuses plus a few extra, and have no bonuses on the side that the players start on. Each country attacks the corresponding country on the other side, plus the countries bordering it on its own side. What will happen is a sort of mass exodus from one side to the other. Eventually, the non-bonus side will simply become a way to travel across the bonus side, since it will probably be filled with ones. Now, to effectively guard a country's borders, you need to guard them on both sides!
I'm sort of a fan of the starting neutrals thing, (both of my current map ideas are like this), because what really can ruin Risk for me is getting a bad drop, or being attacked a lot before it's your turn. Starting neutrals help prevent all of that. It's not just me, either... look at the popularity of the Age Of Realms maps.
As a final suggestion, you could have all of the names of the neutral side be anagrams of the real countries.
"Did you just attack Kakamatch?"
