Whenever you play the scotch game it is more about attacking the center. You usually don't develop your pieces as quickly.
3.d4 is the move that attacks in the center. Which also puts pressure on the e5 pawn. If 3...exd4 4.Nxd4 then white has the center because there are no black pawns in the center, but there is one white pawn in the center which is the e4 pawn.
If you want to attack the center a lot then the scotch game is right for you!
