I’m creating my first 2D-game for Android with Unity3D and I have a target resolution of 1080×1920 (my GUI uses this resolution). Is this resolution too big for a mobile game? I didn’t make the in-game-sprites yet and I’m just wondering that the resolution might be too large (memory comsumption).
Should I support two resolutions (1080×1920 and 540×960) or choose a lower one like 720×1280? Do I have to redesign all my GUI-graphics if I choose a resolution like 720×1280? What about the sprites? How do I make the sprites so they look the same in different resolutions?
