The brilliance of Napoleonic War is the same timer based building and upgrading that was used in Evony Free Forever.  This timer based system is the real-time strategy aspect of the game, and means the player needs to think about what to build next so they have enough resources to build something afterwards, or so they can build a pre-requisite of another building or troop type.  This timer based RTS system means the NapWar player doesn’t need to be there the whole time.  This lends itself to players of other MMORPG games like World of Warcraft or even Evony itself.  As you can switch windows to NapWar and check on your upgrades and if neccessary you can kick off another building or upgrade after the timer has finished.  This is particually useful when playing a game like WoW as when you jump on a ship or griffen to fly to somewhere else, or if there is 2 minutes of down time while waiting for other members of your alliance to gather, you can do a quick window switch, play some NapWar and switch back to WoW.

Also the alliances inside NapWar can take up to 100 people, so if you have an alliance in WoW you can extend your friendship into NapWar and have the same people in an alliance in Napwar.  This will make your alliance stronger as you can talk about either game inside the other game.

The ranking system of NapWar is Prestige.  Prestige is a measure of how big your city is, how many troops you have and how much technology you have.  Building up any of these will make your prestige go up.  Attacking other players takes prestige off them.
Playing NapWar is relatively simple as you can go through beginner quests which teach you how to play.  Once you’re out of the 7 day beginner protection the strategy part comes in.  You need to make sure when you attack someone that you leave enough troops at home so that if someone attacks you then you can defend your city from them.  More Tactics come in as you can now deploy your troops into a rudamentary strategy of defend or move forward.  There is also a graphical representation of the fights and you can even go in and control the fights real time.  This is a new fighting engine and is time and turn based, which works suprisingly well, even on web browser technology.

Fog of War: Napoleonic War is a fun game to play, and with the timer based Strategy system the game player can chose how much time to spend on it.  It could take over your life, or it could be a nice side game while playing another MMORPG.
