I don't entirely believe that It's that, piracy has always existed, this is not what killed gaming interest for you. It's just that old games, mind you, with some exceptions, aren't as appealing or enjoyable to play as they might seem. It's also a mind thing since you can say "ok yeah this game sucks let's try another one". It's like getting the full GBA romset just to end up playing Pokémon Emerald
