Humble have a Halloween sale also -

https://www.humblebundle.com/store/promo/halloweenweekend/

Thanks for mentioning this one, it looks really interesting and something I would have missed with all the current sales going.

Nuuvem has some excellent deals for this Halloween:

http://www.nuuvem.com/promo/halloween

My favorite deal (and very tempting ^_^) is Middle-Earth: Shadow Of Mordor - GOTY Edition, for R$ 29.99 (around $ 7.80 USD).

I tried several items (shadow of Mordor, Resident Evil Revelations 2 being the ones I was most interested in) and every one of them was marked as unavailable upon checkout. Every single one. Mordor was a big surprise considering I have purchases many WB titles from them before.

I.. hate the new Nuuvem. Its just a bloody tease now. :'(
Don't send me emails for games I want, let me add them to my cart, then block me at checkout. Seriously. That is just cruel.

#cartblocked.

They should just block everyone outside South America from using the site, or at least put that info about regional restrictions directly on the game pages. It's ridiculous to invite everyone in and lure them with low prices and sales, only to tell them at checkout that they can't buy anything.

Thanks for the warning. ^^
I heard of that site a couple of times and thought of visiting it.
You spared me the frustration of visiting Nuuvem only to realize that Im not able to buy anything. xD

what was the highest discount so far for trails in the sky on gog?

It hasn't gone higher than 50%, either on GOG or on Steam.

Thanks for the heads up! I'm curious about it, but I've read that there are unfixable issues with running the Steam version of Call of Cthulhu on modern OS like Win 8.1? Something about a ladder or trapdoor early in the beginning, for example?

Some info here. Long story short, the unofficial patch helps, but works better in the retail version as Steam's DRM doesn't allow all the fixes to be applied.
