To be honest, Sim City separates those ones who simply blobbed their way to victory with Axis from these ones who are capable of using their brain.
By the way: Playing versus Sim City was the only challenge that I have faced in 2vs2 AT as double OKW.

It might be frustrating to fight against but seems to be the only reliable counter to halt double OKW's might in late game wherefore I am not enraged about anyone building a city against us.
