The great sequel of Stronghold is now going Online and you can register for it's OPEN BETA right now (:
Follow this link.
I dunno how is the gameplay, but I'm downloading it right now. It looks promessing but I dunno how will this be, I guess you gain technology by each level you gain.
For everybody who doesn't know what is stronghold...Well it is just the best game in castle series (:
You contruct your castle like in the medieval times, you need food, weapons, citizens, hapiness etc..etc..
