Remember guys you can use Chrome to write XNA games on Windows and Xbox 360. Now with the added networking capabilities there should be nothing stopping you. I can personally vouch that XNA almost as easy to use as SDL. It really is that good and quick to get a 2D or 3D prototype up and running. Also over the next month or so I'll be working with the RemObject guys to get Chrome and XNA fully integrated into Visual Studio 2005 and probably 2008.

Go on, jump in, the water's warm ;-).
