Steam will probably never officially support them (as I do).I do agree that having 'id software' push the PrBoom Source Port on the iPhone, but the original DOS version (320x200 with 4:5 non square pixels) in Steam is a little weird.In relation to some of the above, neither Valve, Steam nor id software can sell (for profit) certain 3rd party additions to DOOM. DOOM has been GPL'd for quite some time and I don't see id software approaching any 3rd party developers to package and bundle their stuff with a release. (Final DOOM was kinda like this, but that was a very long time ago, and prior to the GPL'ing).
