Far Cry 3: Blood Dragon (IT'S ON UPLAY NOT STEAM!!!!!!1111oneoneone) (x)KP-NKGB-(y)XCG-WJJL-PE(z)G
y=(4!-3!) lim sin(x)/x as x→0
z=lim 6+(1/n) as n→∞
x=(3!-1)s where s is the sum of the infinite series Σ1/2^n where the lower index of the summation symbol is n=1 (the upper index of the summation symbol is of course +∞)
Have a nice day. :D:D:D

i dont think even normal people are gonna get that one.
try making the code into a jpg image and ziping it. then uploading it in 4shared or mega.co then hotlinking the downloadpage.
that take as long as solving arithmetic and is easier. plus bot can't solve aritmetic neither execute complexe suite of action (follow hotlink->connect->get past the site bot check (if any)-> log in with valid acount if needed-> hit download link-> actualy doanload and analyse file-> determine what archive format-> extract archive-> scan extracted file type-> detect jpg-> open jpb-> scan for code-> fail because its not a text file->someone else who did not sue a bot legitimately ninja'ed it while you where loosing time with your stupid bots/script.

I'm aware how bots work, but thank you for the explanation, nevertheless. The fact is, normal people must be kinda... well... "stupid" would be kind of offensive, so... not-really-well-educated? Also, you actually can solve this with the basic math knowledge. Hell, you don't even need to solve entire equations. :P And, the last but not least, one doesn't have to be university student to simply google the way to solve this (or directly the result, to be honest).
And it's not like anyone needs to get this key, right? If anyone's willing to get the free key, why not to put a little effort, huh?

I think it is great.
People worry so much about bots here and never think for a moment, our primary system favours those who are most practiced at copy/paste combined with typing speed.
It is just a practiced skill, like doing math.
It seems to me they just hate when you adjust the odds out of their favour by requiring actual other skills which may give others not so adept at copy/paste and substitution a better chance.

You may be right. Honestly, I just thought making this a little bit challenging may be fun, although I must admit that getting the keys by those who just copy/paste and type faster than the rest of the people seems to me to be a little unfair and almost as irritating as ninjas.
Also, thanks for the appreciation once again. :)

you built a reply containing several argument about how my opinion is biased/wrong. (even though you dont claim it directly)
i think that was a free hit that i did not deserve.
also i dont think even normal people are gonna get that one. doesnt imply that everyone is stupid.
this here was a very distorded interpretation you made.

Absolutely. Doesn't even have to be just math, these kind of bot protections are fun and get the job done :)

I already have it or else I'd be solving the heck out of that. IT's a great game, and you are correct; somebody with the right skills could solves these fairly quickly. I'm pretty sure I've seen these, or close enough, on exams myself. If you have limited knowledge of more semi-advanced calculus however, you're up a creek without a paddle.

Well si(0)=1, therefore y = 6-24 = -18. I think y is meant to have only 1 non-negative digit in the key, so I guess you mistyped that equation..?
Next equation is easy when lim 1/n = 0 (when n to infty). So z = 6.
The factor 3!-1 on the last equation obviously is 5, but your notation of the summation is very uncommon, because the summation index i does not appear in the sum itself. Nevertheless this yields the sum to be 1/n(n+1) * n = n+1 (when the upper index is n). Therefore x = 5(n+1). For a unique solution for variable x you must clarify which number n should be.
Good thing that I already own this game :D

Yeah, I mistyped the first one, sorry for that and thanks for pointing that out. :)
About the summation index... Well, I always write it below the summation symbol, everyone did, senseis included. Also, it's kinda important what is the value of the summation index. :P
Also, the third one is also a mistype(s). :D Correcting right away. And you're right, I should write the sum of the series some other way.

Now you write
"x=(3!-1)s where s is the sum of the infinite series Σ1/2^n where i=1 (the upper index of the summation symbol is of course n)"
which doesn't make much sense neither. :P
Naming the summation index "i" makes generally sense when this variable "i" occours inside the summation members (nevertheless its not "forbidden" to do otherwise, for example if you write \sum_{i=1}^5 n , you sum up the number "n" 5 times, which equals 5*n). So i think in your equation you want to name your sumation index n instead of i. The second remaining mistype is that I guess you want to say "the upper index of the summation symbol is of course infinity" instead of "the upper index of the summation symbol is of course n".
