What console do you still turn on from time to time today?
In my case, the OG Xbox. The first console I got, so definitely nostalgia tinted feeling. Fable, Dead or Alive and Star Wars Jedi Outcast are probably my most played games on that platform.
I fired up my XBox 360 last year to get a fix of Beatles Rock Band. It's criminal that that game isn't available on modern platforms! Also regretting not having purchased more of its DLC when it was still available.
