Any good strategy/adventure games on the iOS?

Hi, I'm looking for strategic games for my iPhone. I really enjoy games which includes building/crafting stuffs (I already have minecraft. ) kind of like, survival games. Any suggestions? Recommendations? ^^

Battle of the Bulge, The Setllers, iPanzer, Glory of Generals, they are more strategy than anything I know.
The Settlers is strategy and building, improving your game, adventure and such.
Good call with minecraft c;
