PPI - does it matter? Please help.
So I'm working on my first game and so far everything is going ok. I just has a major crash, and all my photos/sounds were deleted, and had to individually put them all back. No biggie, all fixed.
My question relates to PPI. Does it need to be 72 as I have read in some places but not in others? I'm confused about this. Or does it not matter at all?
I've read that all images should be divisible by 4 and that's not a problem at all, I've done all that, but as for the PPI I don't know if I should be concerned. Or would the problem be having an image that is too large (eg 20mb)? Not that I do, it's just a theoretical question. Some of my images are pretty large though. Could file size of the photo then be an issue?
If anybody could possibly help in this department that would be awesome. What I really need to know is if I should start designing my images again on a smaller scale.
