xbox "Backwards Compatibility"

[Monster ninja]

the so called "Backwards Compatibility" for the xbox is a load of rubbish! under half of the games work and some big games like metal gear 2 do not work however, some games people have never heard of are made for Backwards Compatibility mode why is this???? how can they have a Backwards Compatibility when half the games dont work with it! the PS2 you could play all of the PS1 games
