I mean steam sucked for 8 years like 20 years ago. Technology wasn’t the same as it is. They revolutionized the pc gaming scene and I’d argue that even that Steam version was better than the current EGS version. Was it uglier? Yea maybe but it did the job. You could install, manage and launch your games, cloud saves and it wasn’t bloat or spyware. The Steam just kept getting better even if with a messy ui in some places. They do a ton of shit that generates them no direct profit but that makes using Steam a no brainer. And gamers respect and value that even if not all of them.

Heck I’m sure that they very quickly came up with a functional shopping cart at the very least.
