Stronghold Kingdoms will be free
“In 2010 thousands of lords and ladies will join the race for the crown in Firefly’s new free-to-play castle MMO. Sign up for news on how to be one of them!”
If you liked the Stonghold series in the past, that might be something for you: Stronghold Kingdoms will be available for free.
Just some advanced strategy options have to be paid, but they are not really necessary.
