I had a lot of fun with this map. I believe the difficulty rating should be lowered to "Normal" as I had no problem with it, even on Very Hard. Yes, it was touch-and-go, especially as the begining while trying to collect wood and deal with the wolves. But once that was mastered, it wasn't so bad.
There are several nice invasion to deal with and I purposely played it far beyond the point where I could have completed the eco mission. That was simply because I was having fun and wanted to deal with the harder invasions. {grin}
