As its off topic I'm allowed to advertise: http://www.strongholdkingdoms.com/

Stronghold Kingdoms is a massively multi-player online real time strategy game with a Medieval castle building theme. It was developed by Firefly Studios and based upon their commercially successful and popular Stronghold series of games.

So before you look it up, send me a mail and I will invite you to the game (I get gifts!!!). I think you need steam also. The game itself is free.

Great, I was always looking for a game where you can design a castle and test it against invaders. But what is steam?

ah nice. Steam is free, and its amazing. Its like a PlayStation or Xbox but on the computer. So there's a store with basically every PC game available, including free games. Then you have a library of your games. The reason why its available is because its all about the community. Its an online game system. Look it up in this link: http://store.steampowered.com/

Ok. I'm already very happy that steam did not ask me to install any toolbars during installation :D

I used to love the old Stronghold games! Is the world persistant? Is it like the old games?

And yes Steam is amazing, the company has a very good ethos compared to Sony and whatnot. You can get some pretty incredible deals on their market also!

Tbh I've haven't played the other stronghold games ;) but I got to say this is one of the best I've played. If you want a village/castle builder, houses/factions and diplomacy/war this is a game for you. It's got me more addicted than warlight and that's saying something.

Shame I don't have the time this looks really good :(

Shame you cant join :(. Bump I want to invite more people, I get prizes.

When I was younger I played that game a lot, I enjoyed it, I got busy with Real life so I didnt have time to play anymore, I might start playing again in the future.
