Well, with my current project, I decided to make things like my main title screen 1080P, then in windowed mode it will just be scaled down to 1280x720 so it will fit on all common screens in 16:9 aspect.
I read online where one developer, who develops for mobile, which is really scary for resolutions, plus the fact you can have wide or tall.
His main game play area is a square area in the middle, as are his menus, in the centre. He moves the game controls around the screen depending on the orientation which was a nice solution. I says that he creates his source graphics at a slightly higher resolution that his target. So his target is 1080P, so his source is all 2048x2048 and he just scales down as needed.
I don't know if I will target mobile ever, I don't even own a cell phone of any sort, but it is good to keep in mind. I may redesign my scores and other information so it can be moved to accommodate wide screen. Like in my Deluxe Pacman game, you have the two player scores plus the high score in a thin strip at the top, with the lives and other information at the bottom. It makes more sense to redesign this so you have the play area centred and this extra information on the side of the screen. There would be more room and I may add in extra information with larger graphics to fill in the sides and make it look nicer. This could also free up more room for a larger game play area.
If designed right, I could even design it so the score and other outputs could be moved in the future for mobile.
1080p IS the most used resolution. (Over 70%! That can't be understated!)
Wow, over 70%, that makes sense. Thanks for that. Those steam stats would be more accurate for desktop gaming. Most monitors people buy are 1080P, they're also quite cheap these days so that makes sense. I think targeting 16:9 and just having the smaller 720P window and larger full screen 1080P for the game makes sense.
