What to buy..

Alien Isolation, cause of that price glitch a few days ago.

Still have enough for COD:AW and GTA V, but not buying either of them. I will wait until winter sale before splashing some cash.

Save for The Witcher 3.

I've gotten Alien Isolation, Shadows of Mordor, Evil within, and Borderlands. All good, Evil within could be better but still enjoyable.

If you can only pick one I'd go with Shadows of Mordor. I love Dark Souls so Lords of the fallen looks like its for me so I might pick it up soon.

I own Alien Isolation, Shadow of Mordor and The Evil Within, I would recommend either Alien or The Evil Within. The Evil Within has a new game plus mode, which I like as it adds quite some replay value.

Shadow of Mordor has great combat mechanics and the Nemesis System, but lack a lot in other fields.

Alien offers an amazing ambience in my opinion - by the way, it should be played in hard difficulty.

So I would say The Evil Within > Alien Isolation > Shadow of Mordor > ...the rest, no idea, I don't know them.
