This game brings back a lot of memories. I've spent countless hours playing it when it came out in 2001. The gameplay is great, and the campaign is pretty good too. There are 4 clans in the game: Dragon, Serpent, Wolf and Lotus. The battle realms campaign lets you play through by choosing the dragon or the serpent clan, so it has a good replay value. However, the winter of the wolf campaign can only be played with the wolf clan. Battle realms is different than other rts games because you can't summon vast armies in a couple of minutes. At the beginning of a game you have 1 hut, and peasants start appearing in front of it. Peasants can be used to collect resources, build structures and to train them into battle-ready warriors. A major part of the game are the zen masters, who take the role of heroes. Zen masters are leaders of the clans, which makes them very powerful and useful. They can be summoned from a keep and it costs some Yin/Yang, that can be obtained by successful battles.The game also has a multiplayer and a skirmish mode with computer opponents. These features make the game very addictive (it also has great animations). You don't even have to be a rts fan to like Battle realms, so I would recommend it to anyone who hasn't played this wonderful game. Trust me, you won't regret that you spent those 10$ :)
