Don't get me wrong, I WANT to play it. It's the only game in the series I haven't played/beat. I'll preorder it day1 if it gets rereleased for the Ps4 or even if it's a steam release. I am not buying a $70-100~ used console, to get a $20~ game to play it. I'm holding out hope... I've purposefully not watched Let's Play's or Vatvidyaa (or however it's spelt) of Demon Souls so I can be surprised by it... one day.
Seriously, it's totally worth it.
I'm saying that you go ahead and buy them. But in case you did, it'll be worth the price.
