Wanna feel old? This month, Half-Life 2 will be 20 years old and Dragon Age: Inquisition will be 10 years old.

This month, we're celebrating a number of notable videogame birthdays.

Half-Life 2 was released in 2004 and turns 20 this month, as is Metal Gear Solid 3: Snake Eater, EverQuest 2, and Vampire: The Masquerade - Bloodlines (which famously released on the same day as Half Life 2... oops). Half-Life 2 was released in 2004 and celebrates its 20th birthday this month. Other games that were released in 2004 include Metal Gear Solid 3: Snake Eater and EverQuest 2.

What a month, November 2004! November 2014 was not as packed, but it still contained Dragon Age: Inquisition. This game turned 10 years old on November 18. BioWare released Dragon Age: The Veilguard in October. We can't say that BioWare forced us to wait a decade before a new installment in the series.

We're working on a retrospective for some of the big November anniversaries. But for now, I just wanted to comment about the inexorable passing of time. The fact that Warcraft is 30 years old is fine - the '90s seem so far away that I can accept it - but the existence of 20 year-olds who have never known a life without Steam is a medium power liver punch.

Carlo Rovelli says that there is no fundamental variable that can be called time in the universe. Instead, it is a property that emerges from our particular and blurred view of the quantum interactions which make up reality. It doesn't lessen the impact of his quote from Der Rosenkavalier, which he uses in The Order of Time. The English translation of the book:

"Everything slips right through our fingers." All we hold onto dissolves. Like mist and dreams, everything disappears. Time is a strange concept. When we don't use it, it is nothing. There is suddenly nothing else. It is all around us. It is also within us. It seeps in our faces. "

(Sorry but I asked in the title if you wanted feel old.
