It is to late and I convinced myself quciktly to buy earliy one bundle, because they might put good games in it, so that people would post it and other's would get trapped to buy it.

Oriental Empires
Excubitor
World Keepers: Last Resort
Mafia III
The Mysterious Cities of Gold
Inked
Porcunipine
Gladiator Trainer
Tiny Troopers
Construct: Escape the System

PS: If you can't resist you might consider buying a 1USD bundle first, to get an 10% voucher which you can use for the mystery bundle. But rather to gamble, you can take 5€ and buy a whishlist game from grey sites (kinguin has 15% discount this week anyways), and you know what you get for your money.

Wings of Vi
Endless Legend: Classic Edition
The Flame in the Flood
Porcunipine
Serial Cleaner
Inked
Tracks - The Train Set Game
Fantasy Versus
Rush for Glory
InnerSpace

I got boned. Serial Cleaner is probably the only one I am interested in that I don't already own. Don't forget to use your coupon if you bought something earlier in the month IF you buy this.

Borderlands 2
Human: Fall Flat
Gas Guzzlers Extreme
City of God I - Prison Empire
The Mysterious Cities of Gold
Little Racers STREET

The Little Acre
Mad Max
Sun Blast: Star Fighter
Alter Army
InnerSpaceBatman: Arkham Knight
Explodemon
Learn Japanese to survive Hiragana Battle
Tiny Troopers
10 Second Ninja X

I got:
Lego The incredibles
Gas guzzlers extreme
For me it was a lucky mystery purchase since I like both, had Gas guzz on my wishlist. I am satisfied.

Wanted to check my luck :D

Seriously..
got an email to rate Fanatical.com on trustpilot, and had to give them a semi review due to these gamble bundles, and it's alot of the same games over and over again. Making the site feel a bit "risky" and low quality.

Their response:

   You're right, we have gone a bit crazy with the Mystery bundles. We will be making changes soon so please watch this space. I hope you rate us 5* again next time

But as expected, the greed is in charge and another mystery bundle pops. lol. And as usual with a couple new games, but the rest is the same re-picks from all the other bundles.
Did buy some of the first mystery sales cause i didn't have alot of the games. But ain't buying anymore gamble bundles.
IMO not worth supporting this.

When will this madness stop? Mostly re-bundles if not unattractive bundles for a while now. I guess they are trying to make Humble look good. Hmm. Pretty sad since at one point they have a going of good bundles. Good times never last long. :/

Wings of Vi
Badminton Warrior (羽毛球勇士 中国新年版)
Fantasy Versus
Lust for Darkness
Battle Ranch: Pigs vs Plants
Velocity Ultra
Stealth Inc 2
Dad Quest
Injustice Gods Among Us Ultimate Edition

...meh - I activated 2, already have 2, and will be giving the 8 I didn't activate to groups or the community train. At least I got one new unbundled possibly full value game: Badminton Warrior

The selection is incredibly poor.

In Fanatical's infinite marketing wisdom, they are now pitching mystery keys as a promotion that you are qualified for.

An awfully fancy way of asking "do you want fries with that?" 🤣

View attached image.

Added 2 mystery keys to a bundle and got:

Fantasy Versus
Payday 2 Ultimate Edition

😐

I bought 4 of them

The Little Acre
The LEGO NINJAGO Movie Video Game
Jump Stars
Serial Cleaner

I'm conflicted. I voted "Gambling should be banned.", and have never bought a mystery bundle. But with the community train ongoing, I thought this would be an ok source of some random titles to giveaway. So I bought a bundle:

• Lust for Darkness
• The Flame in the Flood
• Snake Pass
• Fantasy Versus
• Circuit Breakers - Multiplayer twin stick shoot 'em up
• Shoppe Keep 2 - Shop Management Business and Agriculture RPG Simulation
• Inked
• Stealth Bastard Deluxe
• Pumped BMX +
• Wings of Vi

I'd never heard of Inked, but it turned out quite popular. So I caved in and bought another:

• Giana Sisters: Twisted Bundle
• The Town of Light
• BeeFense
• Heavy Burger
• Shoppe Keep
• Prehistoric Tales
• Batman: Arkham City - Game of the Year Edition
• Jump Stars
• Gauntlet™ Slayer Edition
• Stars in Shadow

Not that great, and certainly nothing I wanted from either (good for the train). Then I was looking at the deals on HITMAN 2 - Gold, thought it was time to get it before all those Elusive Targets disappear. But, that little devil on my shoulder told me there was a chance I could get it in the Mystery bundle, and Fanatical had just sent a 10% off coupon too! So, yes, I got another:

• The Flame in the Flood
• Shtriga: Summer Camp
• Wings of Vi
• The Town of Light
• Hamilton's Great Adventure
• Californium
• HITMAN 2 - Gold Edition
• Batman: Arkham City - Game of the Year Edition
• Callys Caves 3
• Injustice Gods Among Us Ultimate Edition

I've had my eye on Californium, so that was nice enough. But there it was - "HITMAN 2 - Gold Edition". So, yes, I did buy 3 bundles but their total was still less (but not by much) than buying HITMAN 2 on sale.

Conclusion: Community trains should be banned as they creates gamblers.
