It was never made available here because the publisher decided not to. Why? It is rumored to be linked to a "cow" controversy.
I am in same boat as you but I now buy 2-3 games on major sales which I know I would definitely play. My backlog currently stands at around 200 games most of which I got very cheap or free. You will be surprised to know that even Witcher 3 GOTY was in my backlog for past 4 years till I finished it in December. This sale I bought the last 2 walking dead games, DMC5 and Dishonored 2. I wanted to buy Sekiro too but it is still too pricey for me. Same case with Monster Hunter World. So, I will be keeping an eye out for them in the next winter or summer sale. Till then, I will be focusing on clearing some of my backlogs.
