Shopping advice + I'm an idiot with a short memory

As you can see in the Humble Store, they're discounting both The Walking Dead (both series) and The Wolf Among Us. I would like to buy them, but I bought some extra mangas last Saturday and right now I don't have enough money left in my "fun-fund" to buy both TWD S01 and TWAU. I asked my friends about which one I should buy, but the final result was 7-7. So I thought I may ask random people on the Internet how to spend my money. The thing is I don't have one I prefer, since I played the first two episodes of both on a friend's PC and I like them both equally. Do not consider the fact that TWD costs less, I don't care (much).
So, random people from random parts of the world including R'lyeh, how sould I spend my money?

Now, how can I explain the second part of the title? It's a really creepy story about a cheese-eating dog, a lawnmower and a Lamborghini. It began on 29th February 2000. It would be really fun to tell you all this, but I still have chills if I think about it. I'll just step to the end. Long story short, I forgot I already requested a key for Tropico 3, so I took another one. Since I don't like getting advantages over other people's generosity (aka: CV from free HB gifts), and I'm not really that good with puzzles, clicky.

Ok then, now it's a bit late for me, tomorrow (TODAY!) the clock sounds at 6 am. So... write, I'll read at more or less 3 pm GMT+1.
And thanks in advance for your help, my money's really thankful too!
