Why buy humble monthly? All of the games get rebundled a month later anyways, usually for cheaper

The early access to the main game that seems to never get bundled.

Not all. Plus Shantae got rebundled for the 3ds, not steam, and I think Titan Souls and Grimm Fandango got bundled on tier3. I can't forgive them for GRAV, though.

Have all been added to a bundle after being in humble monthly, and can usually be gotten for less than $12.

Good luck finding a bundle with multiples from the same monthly - we can of course wait a few weeks and pick up most of the monthly's content, but please, don't compare a single game appearing in an okay bundle's BTA to the usually outstanding monthly in terms of content. It's just useless, at least divide down the price with the game's numbers or something..
for example Mushroom 11 is in ~5$ BTA, and was in a 12$ monthly. You know what's not in Eye Candy Bundle? The other 5 games from the monthly. Don't try to compare two things that are so different - the 5$ and the 12$ bundles are not comparable because they have totally different contents.

Depends on the contents. Some of the games won't be available substantially cheaper in nearby future. If you want those games now and the price is right, rest of the bundle is a bonus freebie.

where is southpark bundled? ark evolved? mad max?

Unless I'm mistaken, the third Shantae game was in the Humble Monthly but only the second has been in the regular Humble Bundle or bundled previously.

Exactly the reason in opening comment why I don't buy it. Sooner or later it will be rebundled in the usual style, and my backlog is long enough to wait for it and not get bored.

Last monthly was my first subscribe and was pretty satisfied with Nuclear Throne and Explorers ,looking foward for the next monthly ! =D

The one in the monthly is Shantae and the Pirate's Curse, not Shantae: Risky's Revenge Director's Cut

It's because the adrenaline rushing trough your veins is amazing :D

add Company of Heroes 2 to the list

in short, quickly rebundled will be: cheaper/indie stuff yes, AAA things no

Question is were Mad Max, Alien, ARK, South Park, etc worth it?

You forgot A Fistful of Gun, it was in january bundle, and Towerfall ascension

The way they work, monthly bundles are just a gamble, and you're really buying them blind, except for one highly-sought-after game that's shown beforehand, and that probably won't be bundled again too soon.
So, ultimately, it all comes down to this simple question: would you buy the main game at $12 (or $10.8 with voucher)?
The only time I actually wanted to buy a monthly was for the last one (April monthly), but I didn't have enough money at the time :(

Are those games the reason you'd feel bad about if you didn't get the monthly bundle?

All the expensive games have been more than enough to be worth the price, it also has the benefit of discovering games I didn't know I wanted. Like Chroma Squad. It's really not much considering the combined price of all the games in each bundle, even considering some games get bundled cheaper later.

I buy it for the "teaser" game, and in this case, Mad Max was easily worth $10.80 imho.
The reveals are just a bonus for me.

It's just a small percentage that gets rebundled later (at least that's the pattern I see), one or two good games makes up for other shitty games, it's like finding a gold nugget on a toilet, like this recent one, for me it was already worth for Mad Max, and I really doubt it will get bundled so soon.

Lots are mistaking Risky's Revenge (this Humble) for Shantae Pirate's Curse (monthly). Risky's Revenge was bundled, however it was over a year ago in Awesome Games Done Quick.
