According to this CasualGaming.biz piece, big web games cost far less than you may think to produce.
“If somebody came up with a good game for FunOrb and one that would be good for our infrastructure, we’d certainly talk about it,” said Jagex CEO Geoff Iddison.
“We launched FunOrb with a low budget, adding games every two weeks. The cost per game is less that $25,000. That’s bearing in mind that we’ve got [development] infrastructure already in place and that it depends on [whether it's a] single or multiplayer game.”
Jagex is best know for MMO Runescape.
