It's very similar to the Great Games Experiment but the option to use your embedded web browser technology is a very nice bonus. Unfortunately, the plugin install fails. There's a download error when I attempt to get the plugin to play Bullet Candy. Good luck with it, the gaming/social networking space is going to be competetive.
Is the error with IE or another browser? and what OS? I know Firefox is screwed on vista with .xpi files. I'm pleased by the GGE comparision HOWEVER since pjio in it's raw form was launched before GGE I'm a little apprehensive about where they got all their good ideas from. Anyway there is room for a few more and now that I've got the tech tied down and API requests coming out of my ears I'm sure the next few developments can only help my position. And I made this myself :P
