our collection (mine & my brothers) was pretty much the same, as well as what you have listed you can add in a spectrum, atari lynx, amstrad gx4000 & cpc 464 (i know the horror, blame my parents) ps1. mastersystem, megadrive, saturn & dreamcast, i think at 1 stage we even had a commodore 64.
currently i have my main rig, xbox 360, xbox 1, ps3, psp, ds & the wii. & game equally between pc & xbox 1
