You forgot to include the original X-Box in 6th generation which had almost the same stats as the PS2 but unlike the PS2 all its games came on DVD's while some of the early PS2 games still used CD-Roms. Also for the fifth generation you forgot the Sega Saturn which also used CD-Roms but has a smaller average game size since it almost had no multiple disc games.
