The graphics quality depends on the sale price. I thought the price was more important, but maybe I have to give more importance to the quality ...
For now I try to be affordable and there are not very elaborate graphics. Later I will be adding better graphics at a price slightly higher.
I really appreciate your comments. I understand then that you prefer better quality graphics ... which would be for you a good quality/price? Know any example that may be useful to me?
well for me personally i wouldn't consider buying graphics unless they are better than what i or my friends who i make games with can do ourselves (for examples of our games, check studioeres.com). i would also never buy "pre-made" graphics for my game because then it wouldn't be unique to the game, if someone else bought them there would be two or more games out there with identical graphics, which defeats the purpose of paying for graphics for me. so basically i'd only pay someone for graphics if they were to make custom graphics for my game according to my specifications (and this would naturally be more expensive)
this is just me though, other developers might work differently
