Every single franchise I used to love. Nothing really excites me when it is revealed or in its pre-release period. It's partly because I've slowly been growing out of most gaming experiences, and the fact that I've been burned too many times by disappointed releases.

Final Fantasy
Devil May Cry
Ninja Gaiden
NSMB
Resident Evil

Assassins Creed(gameplay has gotten stale)
Gears of War(story finished with me in 3rd game)
Mario(fun but the same blah blah)
Resident Evil(action over horror now)
God of War(Kratos suxs)

Final Fantasy, way less than before.

Resident Evil, almost no excitement left.

Metal Gear, somewhat less than before.

Silent Hill, I don't even care anymore!

Dead Space and Dragon Age, Dead and buried :(

Final Fantasy and Metal Gear Solid

Was the third game responsible for that?

Dead Space the third game yes. Dragon Age the second one, although i HOPE TO GOD the third one is good again!

Final Fantasy, without a doubt that series went from being a series I wait for to....a series I might never play again
Metal Gear, I don't know this series lost it charm for me.
Mass Effect, that ending will always leave a bitter taste in my mouth.

final fantasy

To me, it´s more than that, it´s the whole damn company.Calling SquareEnix a shadow of their former selves is a compliment, they´ve become even worse than that, imo.
