Pacific Epoch has put together a database of online games in China. All sorts of information and it goes with relatively affordable price, especially if you happen to be an analyst - 500 bucks for initial piece and from then on 100 bucks for monthly update.
This seems to be quite extensive and easy access to Chinese online game industry, so check it out. One thing that is especially interesting is that they promise to offer information on the status of specific online games - is it in commercial use or testing, is it any good etc. I know that I would go shopping if I would actually work for analyst company. Product goes with the name of "China online game sheet, February 2005", I suppose the next update will be called - this will stun you - "China online game sheet, March 2005".
