I third it ;-)
For 2D games we're talking about resizing the whole frame, so you might not have to resize the individual graphics, just have it rescale after the frame has been drawn.
The other thing is aspect ratio. This would be a kind of problem, but i think the solution would be, to set a resolution that the monitor could handle, and then scale the frame into the correct aspect ratio. In other words, if i'm doing a 16:9 game, using a resolution of say 800x600, would squish the image to fit, however, if you resized the aspect ratio to remain fixed, but only scaled the frame, the res of the monitor would still only be 800x600, but the frame would be something like 800x450 centered... (sort of what you do with matted widescreen on some older letterbox movies -- and matted means they adjusted the aspect ratio in the studio, and outputted to a 4:3 aspect ratio display, verses using true anamorphic, where it squishes the image, and the un-squishes it when you watch it on a 16:9 tv)...
i'm really considering highdef tv resolutions myself, but my tv only is running 720p, and i don't have a way to output to it at the moment, and my monitor is not a widescreen monitor, nor does it go over 1280x1024 -- So it would be useful to make a game in say 1980x1080 -- and then have it scale to my monitor's 1280x1024 and keep the aspect ratio intact... for 1280x1024 it would be 1280x720 (which is pretty much 720p hidef resolution there).
Things to think on at least... I'll build my background first, to see if i can't find some system that will do this for me.
