Over 500 games beaten and over 55 games 100%'ed! MILESTONE celebration! [Ended! Answers posted!]

As of right now I've finished 501 video games on PC and in 56 of them I collected every single achievement. This calls for a celebration!

I prepared a few giveaways for you as well as two puzzles which also include giveaways.

Let's start with something modest:

1
2
3

And now let's move on to the puzzles.

1st puzzle is about me as a Steam and SG user. All answers can be found on my Steam profile and on my Steam Gifts profile. The game I'm giving away is non-bundled of course and was published by Namco. There's no CV required to enter the giveaway.

2nd puzzle is about the games I've beaten and 100%'ed. All answers can be found in the first post of this thread.
