Dark Souls and Shadow of the Colossus

I've been thinking for a few weeks now that I should go back to Dark Souls and give it another crack. But just recently I saw a bit of a live stream of Shadow of the Colossus and remember a friend of mine raving about it a few years back. I think these are two games that have aged very well and really deserve to be played fully. Consequently my note here today is more a reminder to me for the future, when I have a bit of time, and if you've never heard of either of these days then shame on you!!
