The story is truly innovative. World building and lores are great. But dungeons aren boring and repetitive. Unless you are a very heavy fan of RPG and you enjoyed The Witcher 1's and Neverwinter Night's item forging system, you should not buy this one.
This is one of the best RTS ever crafted by human race. Battle Realms is truly a unique RTS with so many original and excellent ideas. I can't really afford to spoil anymore. Buy the game when it is NOT on sale (because the devs earned it) and play Kenji's Journey. Then Grayback's.
