In My Lifetime Vol. 1
1. Xbox 360
2. Xbox OG
3. PS1
4. PS3
5. N64
NES, Genesis, SNES were before my time.
If portable systems was allowed. PSP, and GBA would probably make the list (GBC was a gem as well).
When i was a kid i always picked Xbox OG over PS2 because the graphics were better/sharper. Looking back i skipped a lot of PS2 bangers. I got the PS2 a year after the Xbox OG released. The PS2 was just for GTA, and WWE games. Everything else like shooters, sports , fighting games was Xbox OG all the way. Xbox OG is slept on.
Xbox 360 & PS3 was the golden age of gaming imo. This gen had some amazing games but there was a lot of BS, and fukkery from devs. PS4 is #6 though. Definitely could be in someones Top 5. It might be in mine once i finish catching up on games i haven't played yet.
Dreamcast was great, and slept on. But not Top 5
