I have them split in Greatest hits to Normal releases. i sort them by 3 different factors, First party, series and what games i play more, normally pack-ins go first. So with my Wii it goes, Wii Sports then Mario all-stars, galaxy, NSMBW, Super Paper Mario, ect. then Zelda, Metroid and from there other titles in order of how often i play them. As for by system, its in no specific order, from Left to Right, it goes Wii, 360, Xbox, Gamecube, PS2, PC. and on my 2nt shelf it goes from top to bottom N64 with empty SNES boxes behind, SNES, GBC Boxed, DS, Vinyl LPs/Game guides, PS1/ empty Genesis boxes, Magazines and DVDs. Genesis games are in a cassette tape holder with GBA loose paks and GB and GBC are in with my controllers.
