I've used PhoneGap in the past and whilst it worked well enough for a basic CRUD-y app, I'm not so sure about games, especially given the webview is nobbled in comparison to the browser.<p>I'm toying with the idea of building a game I never got around to on my old Amiga and looked at Corono (<a href="http://www.anscamobile.com/corona/" rel="nofollow">http://www.anscamobile.com/corona/</a>). Obviously no good for HTML games but it does look up to the job if you fancy switching to Lua.
