Any opinions on Just Cause 3 XXL Edition? Wizard of Legend is right up my alley, and Project CARS 2 couldn't be further away from my alley.

>observer_
Sundered
Regions of Ruin
The Darkside Detective
Roombo: First Blood (Humble Original)

Next month's Early Unlocks are Tom Clancy's The Division and Yakuza 0.

Good that I didn't bought Yakuza 0 as Christmas present for myself, I would be angry now. :P

Well as i bought it for Project Cars 2 and Wizard of Legend i'm kinda fine.

Was really unlucky with the unlocks though and also feel like they are kinda "cheap" this month.
Q.U.B.E. 2 and >observer_ were already given away on Twitch Prime.
And well Sundered is a game i'm not really interested in ^^. Well better luck next time

Well, they did give 2 good games as unlocks so I didn't expect much. Observer seems nice but I'm not good with scary games :p

Ugh, the initially revealed 2 games for this month are awful. Yakuza 0 is infected with Denuvo and The Division is a multiplayer game. Even if I played multiplayer only games, it's nearly 2 years old now. Which is 80 in multiplayer game years.

That it was tossed in at all means that Ubisoft figured it'd be good bait for the sequel.

Obviously not speaking for everyone, but it wasn't a game I would have played anyway and having seen videos and streams of it, it was like taking a sleeping pill.

Nice, Yakuza was on my wishlist anyway

so Nintendo now sells on humble, but what is the point? unless you are sending keys to other people just buy from the e-shop.

I don't know, for a year I waited for Rune Factory 4 promo and it didn't happen here so when I saw that now they are selling Nintendo games on HB I was like "yay, maybe the will be some good promotion" and then I realized *US only... oh well...

Rapture Rejects is one of the early reveals for next month's bundle.
