Havent played that one, but an FOHer made a very (very) similar game for iOS called Yeti Town that was addictive as hell. I downloaded it in the afternoon, sat on the couch and was in the dark when my battery died.
I really like Unity of Command http://store.steampowered.com/app/218090/
It's a turn based operational level game about the Stalingrad campaign in WWII, like an old Avalon Hill (or newer GMT or MMP) game. If you have heard of those compaines, or just like turn based strategy games download the demo, you will probably like it. Rumor has it there is another campaign and a scenario editor on the way.
