To most people, this will be a mind-numbingly stupid question. Say I'm making a game in 640x400 in AGS. I'm doing the backgrounds in photoshop. I start my new document and I put in my height and width, but what should I put in the resolution? Is there a standard, or a "true" resolution that won't give me either a too large or too small version of 640x400 (or whatever resolution I'm aiming for)? Hopefully you haven't bashed your keyboard with your forehead too hard and can write back a response.
