Mainly for me, NFS stood, at the TIME, for those things, good cars, good tuning, freedom of choice (which just happens to include features like MT) and HEY, they even ran at 60fps and today run at like 300 with no issues, which is sad indeed by modern standard comparisons. Besides, that's more essence for "me" though but MT in any racing or driving game has no excuse, NO EXCUSE not be in.
Also you got the list in the wrong order i mentioned 5 things

It will be forgotten pretty quick, kinda like how the other games were apart from Hp:2010 as it actually had a good game underneath it, UNLESS they keep up with post support...and ya know...
CREATE A FORUM ON EA.COM TO DISCUSS NFS GAMES ON WHICH THEY NEVER HAVE DONE SINCE PRO STREET! Which is utterly, utterly shameful. Shows how much they care for their product, NOT.
@TiZzla Lol it will be because it's the way they make PC games these days, lack of effort. Expect parity and terrible options mentions and lack of PC basics in the GUI.
