Had a lot of fun playing this one. You begin with a narrow, prebuilt castle, already running. Soon, several packs of wolves will cease your expansion. And the lands are wide, unclear and thus not easy to defend.
The player is given some time to build up a village and a force. Widely Restricted weapons trading, no tower engines. Then, you will be tested by Pig invasions and a large Wolf attack. Cool scripting: while the Pig's men are still fighting, the Wolf announces his soon arrival.
An idea of these challenges and a story should be provided in the description above to lure more players into the mission.
Few bad events might have made the gameplay more thrilling and busy.
At last, the invasions were just "hard" on very hard.
