[STEAM] Halloween Sale (ENDED) | What did you get? Is it as good / spooky as you thought?

Prices are already updating! Let the madness begin (or perhaps not, time will tell). Share the treasures you find inside the candy bag, this year... deals, bundles, glitches, our awesome community shall find them all. Decisions, decisions...

CURRENT STATUS: Ended. Sleeping for another twelve moons, until it rises once more.

Wishing everyone a good Halloween / All-Hallows / Dia de los Muertos / Samhain season, whether in celebration or introspection.

29/10/2018: Sale has begun. Steam has learned from past mistakes, and began updating prices a bit earlier than usual to avoid store overloads. It worked.
01/11/2018: Sale has ended.

For deal comparison, here's last year's Halloween thread. This year, and until we have collaborative threads, it's best to let people discuss and share instead of trying to aggregate all offers ^^

Also, be sure to add season-appropriate GIF's, for added entertainment (not much fun in just looking at prices repeatedly).

Compiling some of the titles people have found. Please don't expect to-the-minute updates to the list, can only get to it after work, so please be sure to check the comments section for the community member's great finds!

NOTE: If you use the Extended Steamgifts script, you'll see the respective store widgets. More visual clutter, but rather helpful to read the list.
