Giveaway Tree (Patience is a Virtue Pt. 2) [Giveaways Ended, Last Update]

Open

Not long ago, I made a giveaway train with a thread titled Patience is a Virtue. To those who participated there, you might have discovered it was a very long train indeed. Portal 2 was waiting at the end. The idea was to test your patience, and to some extent your attention to detail and sanity.

This time, and to celebrate my 6th Steam birthday, I present a giveaway TREE! Unlike a train, a tree does not list all the giveaways in sequence. At each giveaway, you can choose which branch to climb, going ever higher (all giveaways are level 2+). Some of the highest branches will bear rich fruit. Namely:

Bioshock Infinite - Columbia's Finest
Crusader Kings II
Poker Night 2

Finding all the giveaways may pose a logistical challenge. It's a tall and wide tree, and there may also be a web connecting some of the branches at the Sky Edge, a Legendary giveaway if you will. Only the keenest eyes will gain entry to that one.

What are you waiting for? Grab hold of the trunk and start climbing

(Oh and by the way, a bump to the thread every now and then would be appreciated.)

UPDATE 1: Giveaways have now ended. I'll update the thread soon with more info.

UPDATE 2 (read below)

Many of you would have noticed that that each giveaway in the tree was accompanied by a number in binary. These numbers went from 1 to 63, so there were 63 "branches". Each time you climbed to the left, you mutiplied the number by 2 (equivalent to putting a 0 on the end of the binary number). Each time you climbed right, you multipled by 2 and added 1 (putting a 1 on the end of the binary number).

The structure of the tree, much like a mathematical fractal, was exactly as shown in the first attached image. If you counted all the line segments you would get 63. The smallest segments were 32 in number (the top of the tree).

The so called "fruits" were at branch locations 101100, 100001, and 100001.
Also hidden in 5 of the highest branches were five letters which if put in the right order revealed the Skyrim Legendary Edition giveaway. The correct order for the letters was simply the same as ordering them in binary from smallest to largest.

The five letters could be found at locations 101111, 110011, 110111, 111011, 111111 (47, 51, 55, 59, 63)

Setting up these giveaways was quite a challenge. It took a spreadsheet and some fancy functions to mostly automate the creation of the descriptions for all the giveaways. Working out which links to put in each description was not too hard if you looked at it from the binary side of things. Left was multiply by 2, right was multiply by 2 and add 1, and down was divide by 2 and round down.
