If you've never had the opportunity to witness the glory of the Dark Souls series, consider yourself extremely lucky as you can now grab most of it for a relatively small price. And best of all, Dark Souls 1 and 2 come with all of the DLC packs included, so if you're looking to get the most value out of your money the Souls series is a safe bet!
So what are we looking at here? You can grab the full version of Dark Souls 1 at a 75% discount which brings the price down to $5/€5; the remastered version of Dark Souls 2 at the same discount for $10/€10; and finally you can grab the base version of Dark Souls 3 at a 35% discount for $39/€39. Since the DLC for Dark Souls 3 hasn't even come out yet, there is unfortunately no discount available, but I wouldn't worry too much about that as Dark Souls 3 has plenty of content in it as is.
Now I'm sure the big question on your mind is, "I've heard that Dark Souls is insanely hard, so should I even bother with it?", to which my answer would be a resounding yes! The Dark Souls series is difficult, have no doubt about that, but its not the sort of difficulty that will drive you insane with bullshit mechanics and cheap deaths. Every single time you die it is going to be your own fault, and through each death you will slowly learn and improve until one day you finally realize that you've become a rabid Souls fan just like the rest of us.
It is my favorite series of all time, and this is not a statement I say lightly, so if you have even an inkling of interest for Dark Souls - heed my advice and give it a try. Worst case scenario is you lose €5, while the best case scenario will give you the gaming experience of a lifetime - something you will wish you could simply forget in order to play it once more as a complete rookie.
Oh, and there are also a whole bunch of other Bandai Namco games on sale as well, so if you're looking to stock up for the winter, give them a look.
