First puzzle ever and first puzzle I managed to almost fuck up while setting it up (yes, that deleted The Ship giveaway it's part of the mistake), but, hey, it's still doable. So, it works like this: there are 4 giveaways, the first 3 contain a piece of a key needed to unlock the 4th. You start from the first and solve some puzzle to get to the other giveaways.
The 4th is a giveaway for Fallout 3 GOTY, if you already have it you can ignore this puzzle or do it just for fun.
All games are tradable, When the giveaway ends I'll invite you to trade on Steam.
Usual rules for puzzles apply, no sharing answers, links or hints.
You have a week, more or less.
GL!

SOLUTION

• Start here: this is the link to the first puzzle;

• The description said: "Let's get started! You should be pretty used to this by now, simply answer all the questions and get the link for the first giveaway. All the answers are pretty easy, except for the 7th, which is pretty hard. Good luck!". Hence, all the answers were "pretty easy", except the 7th which was "pretty hard". Yes, I totally gave you the answers from the start. All the questions made sense because they were red herrings. When solved you get this link for the first giveaway;

• There are urls hidden in the Lorem Ipsum, some are a clue, some are red herrings, some are awesome. The clues were:
  http://thisissixthiguess.com on a "u"
  http://thisisfirstbutnocap.com on a "Q"
  http://aftersixth.net on a "c"
  http://putthelettersinthebin.uk on a "a"
  http://thesecondandthirdareuppercase.com on a "a"
  http://thiscomesbeforethefifth.nz on a "b"
  http://thelastfourareallcaps.net on a ","
  http://therearenotzpityitissecond.uk on a "."
  http://kisfifthsislast.it on a "e"
  http://lolkiddingitsthird on a "r"
  http://thisgoesbeforekanditislow.it on a "b"
  Putting all the clues together you get this link which contains this link for the 2nd giveaway;

• This was a bit tricky maybe, because you had to use those number and symbols to draw a character in the numpad. For example, if you fill the -/*96543+.0 keys in the numpad I gave you, you should get the picture of a "3". The shift meant "this goes capital". So:
  -/*96543+.0 was a "3"
  -74102+369* was a "w"
  SHIFT-7410.+ was a "L"
  */-7410.+365 was a "6"
  SHIFT-753+*910 was a "X"
  It's the code for the 3rd giveaway

*At this point you should have all the parts of the key for the final giveaway. Those are roman numerals. Convert them to decimal numbers and convert the decimal numbers to ascii characters, then decode with a base64 algorithm and you get this.

That's all folks, thanks for playing!
