I got a PS4 in the kerayzee deal on Amazon a few months ago (PS4, WItcher and 3 months + for £200). Loving the game, though it's got a bit repetitive now (I'm on Ugly Baby mission). I put it on Death March difficulty and really struggled at first, multiple creatures are really awkward though multiple humans are pretty easy. Once you've got fighting technique sussed then it's pretty straightforward. Loading times are a bit of a pain, but just try not to die. I try and draw most opponents away and dispatch as 1vs1.
A stash would be really good, constantly carrying around 150+ worth of stuff with a 160 limit. Annoying that all the armour I seem to have crafted is gazumped by stuff for sale by merchants. Also don't see any point in adding runes to swords or armour, makes very little difference. Some of the UI in the inventory is a bit clunky (probably why I need a stash).
