Well you are comparing new games to games that have been remade several times!
Let's take the example of Final Fantasy IV. It was originally released on the Super Nintendo. Then it was re-released on the PS1 and after that on the Wonderswan Color(in Japan).
Then it was re-released again on the GBA and then remade in 3d on the DS. As you can see this is the 5th iteration of the game(4th if you don't include the JP only WSC release), you can't expect it to sell insane numbers after so many re-releases of the game.
FFIV releases:
1) SNES
2) PS1
3) Wonderswan Color (JP only)
4) GBA
5) DS
