Just bought it since its in sale and the "demo" version I tried had a fucking bug that made balin and his brother do almost nothing in the starting bridge mission. I started on normal but felt it was a little bit easy but since this is extremly early the difficulty may be getting higher later or should I just play on hard? I am not fully retarded but I suspect I am not as good at these games as many here.
Play on Hard. Just make sure to don't ditch Balan. You need all the tanks you can get early on.
