I notice that a lot of entries aren't playable in the browser.  It leads me to wonder if there are lot of people who avoid browser games.  Do some of you only play those games you can download?  Perhaps it's an issue with bandwidth or drivers?  Are you having problems porting to html5/js?

It hadn't occurred to be to cater to both.

I personally prefer browser games to downloadable games.

I think there are a lot of downloadable games due to engine limitations, or as you previously stated problems with porting. Or it could simply be personal preference, who knows!
