Ei How Yang maybe. but he can kinda be linked to Yong Yong too. its a bit of a mystery really. I just don't think Sachen would keep a full development team but not release a single original game between 1994/5 and 1999/2000 - they probably hired a few people back (probably including EHY) to develop those two games, or outsourced development to whatever company he was working for at the time.
