ADDITIONAL -

If you're looking for the list of items that are NOT a part of the standard 50% off sale, please go here.
Hit the post size limit so I had to put that list elsewhere.

Good for you to take the lead on this, count on my support :D

I appreciate that. Should be a fun (teeth-gnashing) 48 hours. ;)

Also, the Atlas bear count is at 1 already. Got hit with it doing the first edit. That's really auspicious....

Hurrah! I'm free! FREE I TELL YOU!!! ;D

I mean, ta, nice work.

my body is not ready yet !

You know that according to some twitter thing it will last until 15th december? :p

Ah, it`s live now, and quite a lot of games on flash deal at once!

oh bloody hell its true and its live till 15 dec

I think we have enough crazy people here to do it :D

yeah!! Be interesting to see how many times they will repeat this time....

Says "FALL SALE" on my PC...

D&D Bundle on the first day, how shocking :)
It`s practically their trademark, without which I cannot imagine any GOG sale.

Nice! You can count on me too. :-)

And we're off. Lots of new titles in the Flash Deals, it seems. And hurrah, Dark Dungeons! Get it, folks, it's fab.
