The only ones I've seen sell for significantly more than RRP are Breach and Clear Vita, the PS4 version of Saturday Morning RPG, the Shantea games and the first Oddworld game.....Most of which I offloaded except for SMRPG PS4 which I'm keeping as I'm collecting PS4 games and I think this is one of the most rare (Yeah I know call me a scalper if you want, but I only got one copy of each) . I also have Night Trap PS4 for nostalgia reasons, I remember the uproar about that game back in the day.....God I feel old
I'll buy a LRG game if it takes my fancy but most are not great games IMHO.
Another thing about LRG is the amount of loose discs, but I think that's a PS4 problem in general, maybe not even limited to PS4, whoever is making the bluray G2 size cases is cutting corners.
