My younger brother had a Gameboy, Sega Saturn, PS2, PS3
I had friends that have owned Sega Mastersystem, SNES, N64, Dreamcast, GameCube.
So between my brother and friends it fills the gaps I didn't have.
I got to play most consoles to some extend minus the older ones like Spectrum, Amstrad, Jaguar, Atari etc
