In another thread today I stated that there are only a few series that deserve AAA.
Mario, Zelda, Final Fantasy, Halo, Grand Theft Auto, Gran Turismo, Pokemon
and maybe: Metal Gear (Solid) and Resident Evil
AAA does not describe a particular game that scores high, it's about series that throughout the years delivered quality, very high sales and system selling abilities.
Imo AAA is used far to often on these forums these days.
