Would David Fincher's Se7en be any better if the revelation at the end was that the box contained a pile of indie games for almost no money at all? It would certainly be less psychologically damaging to Brad Pitt to discover the Lovecraft inspired platformer Eversion in there instead of (a box of fluffy kittens for sale - spoiler ed). And while he lived happily ever after he could think back to that lovely day when he and Morgan Freeman and Kevin Spacey all hung out in a dusty field playing indie games. That's the power of cheap indie games, people: they make you forget someone killed loads of people in really horrible ways.
Anyway, to answer the rather insistent detective, the Eclectic Bundle has no theme. To know 'what's in the box?' is to know about a random assortment of oddball games. For the minimum price of one dollar, you'll be handed the delicately eerie platform Eversion, the deeply dwarvy Delve Deeper and its DLC, the strategic oddness of War of the Human Tanks, the popely pulp of Shadows of the Vatican - Act 1, and Fibrillation. That last one I'm putting a video of below, because I hadn't heard of it until now and I have a sneaking suspicion that it might be an official sequel to Se7en, reuniting everyone who made the original, but in a game. Let's watch.
Oh well. I've played two of the games in the bundle and can tell you Eversion and Delve Deeper are definitely worth a dollar, and maybe a few coins more. Generous backers who pay more than a paltry $2.70 will get The Adventures of Shuggy, Stay Dead, The 4th Wall, and Flibble in their 'box' as well.
