What are you must have purchases this Steam Christmas sale?

Helldivers
Rougelands
Reflex if it went 75% off
Assassin's creed black flag, heard it's the best one around and its def gonna be 75% off

Maybe: Naruto bundle/ ultimate ninja storm
Dragon ball Xenoverse
Elite dangerous

I want to get Train Simulator 2016 with some proper DLC. I've been frustrated with Trainz for so long I need something better.

Resident Evil Revelations 2 - complete season

Every A. Creed game up to Black Flag but not A. Creed original.

+1 for Hand of Fate. Got it during the halloween sale and it is such a good game. Also, they recently updated it with free content so I would put that on top of your list :)
As for me, I don't really have must buys for the winter sale, but I will keep a close eye on my wishlist price drops.

I don't have any "must have"s, usually I just browse and pick something I'll consider playing if it's on a decent discount.

I'd say I already have about the most major release of this year, but I don't have much time to play them or my SG wins from start to finish. My gaming routine is "some Rocket League matches after work and off to bed we go".

I am interested in Armello and Hand of Fate. Hope they will get decent discounts.

Dark Souls 2: Scholar of the First Sin
Undertale
Rocket League
Hopefully atleast one of them goes 75%

I really want 3 games: Nuclar throne - The forest - Killing Floor 2 but i don't believe they will have a big discount.

7 days to die, stranded deep, arma 3 depending on the discount :)

I'm having a deja vu: I could swear I wrote my comment here, but I can't find it =o
Can't say those are "must buy", but I wouldn't mind getting them with a discount:

• Mad Max
• Space Engineers
• Infinifactory
• STASIS
• The Flame in the Flood
• Soul Axiom
• Shadowrun: Hong Kong
• Submerged
• Rebel Galaxy
• Cradle
• Technobabylon
• Elegy for a Dead World
• Layers of Fear
