Although the game is fine, In all honesty it was not my favorite part.
The encyclopedia offers an extensive account of the officers and progression of what really happened during the war. You can look up almost any officer in the game, and the encyclopedia will detail their involvement in the war. Now, I know some of you are saying "Why the hell would you get a game for just the encyclopedia?" well, I did not get the game for simply the encyclopedia, but it is one of the coolest features I have seen in a game, simply because of its sheer, extensive detail. I have a difficult time finding a more in depth account online. (I might just be searching in the wrong places, lol) So the game is fun, and its encyclopedia is detailed, but you have to wish KOEI would add a greater amount of innovation. It seems whenever they add something great, they end up taking away one of the better features of the bunch. But the game offers enough to keep me hooked, so I digress. I can't wait for Empires!
