Found it pretty quick.

It's a really cool list. It includes every game released in long box format and indicates which of the three long box versions the game was released for:
Long box clear jewel case (same as Saturn and Sega CD)
Long box bumpy ridge (strong plastic case - the good kind)
Long box flat cardboard (never liked this kind)
It also lists which of those games were released in regular CD jewel case.
What was the reason for the Playstation 1 games having a few game released in long box cases? I am guessing that they had a second print of same game that which was then switch to a jewel case?
I can't say for sure, but I'm guessing that they were originally released in long boxes because, at the time, that's how disc based games were released (Sega CD, Saturn). I'm guessing they swithced to the plastic long boxes with the bumpy ridge because the jewel cases were too brittle (these were the best kind of long boxes). I'l also guessing that they switched to the third type of flat cardboard long box to save on costs.
Eventually, the swithced to standard CD jewel cases. The long box games that were re-released in standard CD jewel cases were simply popular enough to continue production into the new style. Some were even poupular enough to get a Greatest Hits vesion in the standard CD jewel case format.
Did you check out that link I sent you? I think it's helpful in determining which games were released in each style.
