PS4 & PS5 cases are not the same format as PS3/Blu-ray cases in regards to the cover inserts themselves, which are vertically wider than covers made to fit PS3 & Blu-ray cases. Therefore, I think there should be a new "PS4 case" selection made available in the "Case" field when uploading new covers. So far everyone uploading PS4 & PS5 covers have had to choose "Blu-ray case" which is inaccurate. True, both cases are made from transparent blue plastic, but they are essentially different cases altogether.
I myself design custom covers for both PS3 & PS4 games, and I would like to feature them and make them available for download here. However, I would like to have that issue corrected beforehand, if possible. Especially because my PS3 covers are designed to fit PS4 cases, and not PS3 cases. For anyone who prefers the newer PS4 cases over the older PS3 cases, and wants all of their PS3 games in their personal collection to match up with their PS4 & PS5 games.
