It's 2am in the morning when you posted. Right now, there's only 2,292 people online (it peeks at around 10k during the early evening). There are currently 11 open games as I type this (2:32am).
Are these stats publicly available somehwere? Even it's just the current numbers without any stats. This way we could create something like
this for Demigod. (Or maybe you guys will do such graphs too?)
