I played PC games since the early 90s, so I am well familiar with how things used to be before steam. And it was fine. I was hesitant to use steam at first, because like you say, I simply didn’t understand the point of it. Sometime after Valve released the orange box, that ended up being the first thing I bought on steam. And back then, some of the first things that I noticed about it was the ease of installing games, and the friends list that let me talk to and play games with my friends. I ended up getting really into team fortress 2, largely because I could play with people I knew, and we could even chat outside the game easily. It was easy to buy other games that these same friends were playing, and then enjoy a different game with them.

I got used to steam and it began to feel convenient, and at the same time, physical media started dying off. Steam let me easily install and uninstall any of my games whenever I wanted. I didn’t have to keep track of any physical media. I don’t have any of my old PC games from the 90s anymore. I have no idea where there went or how I lost them. But they are just gone. However, I still have every game I’ve ever bought on steam.

I’m not a heavy gamer anymore. If I see something I want, it’s easy to just put it on my wishlist and wait until it goes on sale at a price I think is reasonable. If I feel bored, I might open up my full list of games and browse for something to install. My game saves get backed up to the cloud. My controllers just work. Everything related to the gaming experience is integrated into one place, and I like that, it makes it easy. And for the most part, steam kind of just stays out of my way.
