This total overhaul of Rome:Total War is based upon the Second World War. It contains historical battle locations on different fronts.
Dagovax has been hard at work on this mod, and has improved a number of factions - Guomindang (Chinese faction) has infantry, an officer's car, a prototype tank, planes and an odd sword-unit or something.
The mod is taking place between 1942 and 1953 - so the Chinese may very well develop things they did get after WW2 if they survive long enough.
