If you are inclined only towards a console, then it's a separate thing, otherwise, no console matches and beats a Gaming Rig!
Coming towards PS or Xbox, both come in 2 variants; PS4 Pro and PS4 Slim & Xbox One X and Xbox One S. Both have their dedicated titles.
PS4 Slim and Xbox One S are comparable to one another in terms of budget. Both have their respective strengths and weaknesses, but still, PS4 Slim is the overall winner in comparison to Xbox One S!
It will cost you around Rs. 35-36 k, and you can buy it from online retailers / sellers too... Like daraz.pk, etc. For Shop, I think Kiran Electronics is the best. They have different shops across Lahore, you can buy from any of it's shops.
Regarding Games in FPS category; COD series, DOOM, Uncharted 4, Metro Redux, Far cry series, and my all time favorite, Wolfenstein series (The new order, bad blood and the new Colossus)!
For survival horror, Resident Evil series, The evil within, Alien Isolation, Until Dawn, dying light, prey, and, the winner of its genre; The last of us...!
(I am too only FPS type and have played almost all the popular titles since 2016. Then I got selective and since last year, haven't played even a single title )
