"Mobage Open platform Forum 2010" was held in Shinagawa, Tokyo on June 4. It's DeNA not to mention sponsorship.
The conference report is here. (I yet not all write it. (；´Д｀) )
These are states of the parties.
The Japanese social platform SNS are three kinds of "mixi" "Mobage Town" "Gree" now.
But, Mobage Town seems to be most successful.
DeNA CEO Ms.Namba says, Mobage Town's PV is about 2 times of mixi and Gree. And, 241 social games were released in a half year. Furthermore, the offtake of the virtual currency doubled 10 in a half year.
Magnificence of the cooking of this party shows success above all! (^-^)
