I actually think that Kartia photo you have listed is legit. All the copies I've seen with that style shrink wrap have a seam running up the back of package. There are quite a few multi disc Playstation games out there that don't have the Y-seal or have both types.
All of the single disc games I've seen have the Y-seal and security tab. Depending on where you bought them, some of the later release single disc versions, may or may not have a hang tab on the back (Final Fantasy Origins for example).
The long box sealed games are not as easy to spot a reseal. There aren't any security stickers and have many variations. Games like Kileak, Street Fighter the Movie, Rayman had a crinkly shrink wrap like many of the games in the early Saturn cases. The stretchable style shrink wrap was used on many of the cardboard and plastic spine boxes. If you come across a Psychic Detective, the transparent tape under the shrink wrap holding the box sealed is normal.
I personally only buy the Greatest Hits versions if that's the only option available, like Virtua Fighter 4 Evolution PS2. If you're a completionist or don't care which version you have, that's up to you. It's your collection.
The shrink wrap is not always going to be perfect and the security stickers won't always be aligned either. The occasional misprint like FFVII is obviously out there as well.
These are some of the multi-disc jewel case games I know of that have the standard shrink wrap. I'm sure there are many more. Please note, some of these also have Y-seam versions as well. Hopefully other PS1 collectors chime in here to add to the list.
All of these have hang tabs.

Are you saying that Kartia: The Word of Fate, Legend of the Dragoon, and Legend of Legaia all had legitimate shrinkwrap (not Y-Fold) sealed (not resealed) versions of the game?
I'm not sure if I remember correctly but I think I remember when I first got my playstation I got those games from the store and I think I recall them being Y-Fold.
I'm not really going for a complete PS1 game collection. I really only want to collect my favorite games in Mint Condition and full versions of the games I played as a demo version that I thought were fun.
I would buy a Greatest Hits copy of a game but I would keep looking for a Black Label copy because the Black Label has the complete front image Cover Art but the Greatest Hits has the Greatest Hits label on the Cover Art instead of the complete front image. Some games also have a variance in the CD color, such as the Black Label had a full color CD and the Greatest Hits had a Silver and Black CD.
