COHO was aimed at the casual player and also at eliminating piracy in China with the FTP mode. It was launched in China first.
COHO could never hope to compete with COH1 competitively, from which it was derived. And to that extent, serious COH1 players often held COHO in near contempt. Nevertheless, COHO was fun to play - its multiplayer was far superior to COH1 (Hero units etc notwithstanding).
