Anyway I've just read a blog where someone claims to have started playing Demon's Souls on 4/11/11, finished it and earned the Platinum on 18/11/11, a total of two weeks. He then goes on to claim that he (I'm assuming it's a he) began Dark Souls on the 10/12/11, finished it on the 20/12/11, played through newgame+ the next day and earned the Platinum on the next day, 22/12/11. Oh and incidentally he was only able to play at weekends.
I would love to know how he managed to get all the materials needed to upgrade all the weapons in Demons' Souls (Pure Bladestone anyone?) and given the complications that World Tendency introduces, it seems hardly possible.
As for Dark Souls, we all know that to get the Knights Honour Trophy you have to play the game through two and a third times approximately and on top of that some of the weapons like the Channelers Trident are random drops. I can only guess he used Player Trade but, of course, he didn't say that.
Sorry to ramble on but I'd like opinions on whether this is possible.
