GREAT CONCEPT! There is a lot of vairty in just one class of soilder, in most games of this nature you might just have crossbow men and archers, you have other type of bow type of soilders so you have to vairty of soilders.
Besides that, the game falls flat and is simply broken. Yes the dreaded broken game my friends. I played and played level 3 a several times, and can't beat it because the game doesn't want me to, it's not due to lack of trying or being defeated....It just freezes on the level after a half hour or so.
In any game, buidling your castle is one of the most fun parts, it's a freak'en nightmare. Nothing lines up, even when you think your walls are together they aren't, for some odd reason. When you finally do get your castle walls straight it seems like you only need a handful of bowmen to fend off any baddies.
The AI took the short bus to school, they charge your castle in small groups sort of like they are hazing you and testing you out but they end up accomplishing nothing.
It does have an interesting system when it comes to getting resources, you just don't chop down word, you have to make them into planks with a special production house. I like the mirco mangement, and you can switch workers from job to job. I like RTS games where it takes time to raise an army and it's not just about who can build the fastest army first like starcraft.
I would have finished the game dispite it's flaws but at the end of the day when a game is broken and can't play you can't give it a thumbs up.
