What is the First PC game You Have Ever Played?

I started playing PC way too young can't really remember but because I really used to like King's Quest IG and Solitaire. I will go with the two but the problem is that I don't know which I played first but I did really loved solitaire.
 
I can't remember the name of the first PC video game that I played but I know that it was a space shooting game. It's been so long since I played on PC for the first time.
