What was your first game on PC

My first game was Runescape back in 2004/2005. I was really horrible at it and made no progress but it seemed so fun back in the day. The game currently offers two versions and one of them is how it was back in 2007 so the nostalgia is immense when I play it now.

As for an actually video game such as a steam game, I believe I started playing Garry's Mod in 2013 where I got addicted to Trouble in Terrorist Town. I switched over from Xbox 360 because I was kind of over the Call Of Duty series after Black Ops 2. I do have to say though Origins from that zombie series is still my top Zombies map to this day.
