First Steam purchase?

Hmm it's hard to say..I just made a new account for my steam and I purchased dead by daylight off the bat since its an easy game to run on my computer and I love the ranking system since it's such a simplistic meta for my free time when I don't wanna play anything too intense... However I think the first game I actually purchased was either The Orange Box or CS:GO. That was a few years ago.. Still looking for some easy sandbox style games to play since I need install a new HDD drive since my SSD is already almost full. FeelsBadMan
