1. PS1.
2. PS2/GC/PC (Warcraft 2/3) — when I was into Warcraft, I pretty much ignored any consoles.
3. PS3 - first console I got at launch.
4. PS5.
PS4 was nice and all but I wasn't as invested into gaming that generation, I was playing a little bit towards the start of it and then kinda came back towards the end, a year or so before the PS5/XSX gen started.
