Why are their small pieces of foam block in some of the longbox PS games (the cardboardish ones only i think)
I'd assume they are present to reinforce the cases. I've also only found them in the full cardboard & half cardboard/half plastic longboxes. The size is probably so small so that you don't have to take the foam out when grabbing the game CD or putting it back.
Nice find by the way with the import games
