When someone talk about hard games on the PS3, the very first thing people would say is Demon's Souls(or Dark Souls obviously). This games follows a risk/reward system as you WILL die in this game and you only get one chance. There's no bank, no second chances, no way to put off the inevitable. You will die in this game. When in this soulless form, you'll be permanently stripped of a chunk of your life meter. But even so you will continue to go back as the satisfying feeling of finally completing a stage after over 50 tries is so damn good that you will keep going and going into a a endless abyss of darkness. This game easily tops off as one of the best games on PS3 despite having not any kind of special plot that shines out from all the other JRPGs. The soundtrack is cool as it gives off the eerie feeling of being alone and then suddenly pitted off a huge boss with a song as if this is the very end. I could keep going on and on about this game, but once you tried it. You will seek for more.
