NFS Pro Street and PS2 version Most Wanted

I don't understand why you don't have NFS Pro Street and Most Wanted (the good original one) available to purchase on your site! They are classics just like Underground 1 and 2! Please bring back these classics. I understand graphics slowly get undone by the next gen and even controlability go out of the window at some point but these are games you really should have in your library perminently. And until Underground 3 comes out I need my fix of this style of NFS so badly! I'm definitely not the only one!
