From what I gather it's best to create your game in 16.9 and use scale mode. What I'm still unclear about is how this deals with the issue of smart phones, tablets etc... They have a vast range of resolutions. Should I be creating a game in the highest possible resolution supported by mobile devices and make sure it's in a 16.9 aspect ratio? Or have I completely missed the point :P.
Searching the forums though, it seems clear to me that the supporting multiple screen sizes is still a grey area. Maybe we can thrash this issue out once and for all and eventually sticky this?
Thanks for reading :)
