Thoughts: Rush for Berlin Gold?

I've been perusing the Amazon sale, and I came across Rush for Berlin: Gold for only $1.25. Since I've enjoyed other WWII real-time tactics games like the Stalingrad, the Blitzkrieg series, and Men of War, I was interested in this one. Anyone have any experience playing it? I'm wondering (1) if it's any good, and (2) if it offers anything unique or different from the other games in its genre. I know it's really cheap, but I'd rather not waste money if I can avoid it.

Thanks!
