What date in your life would you like to travel back to? Maybe to the 6th of September so you can think about this quiz longer!? Sounds reasonable.
With this post I'll bring the thread back up and give you some hints.
Clues #1: 1) One series is featured several times in this round. 2) Game 11 is the last part of an older trilogy. 3) In the first line of this puzzle, only #2 has never appeared on Windows PCs. 4) Number 12 was released in this decade.
I'm going on holiday tomorrow, so here are the second and last clues already today.... because I don't have a time machine, unlike many of the protagonists in the games asked this time.
So let's go: 60 people are already participating, and one week from today this round will be over.
Hints #2: 1) You control games 3, 6, 11, 12, 14, 17, 19, 20 and 21 from a first-person perspective. 2) Title 15 is a Metroidvania. 3) There is also a VR version of game number 3. 4) The nine titles with a first person view are joined by five from a 3rd person perspective and eleven with 2D gameplay.
