Theoretical wins are achieved more quickly. That is, a win takes fewer moves in general. When your opponent elects to resign is a different matter.

The reasoning stems from endgame fundamentals. Look at the concept of "the square" in king and pawn endings. Now the board is rectangular, which means, by default, you can swap down even from all minors to just pawns and be in an instant win. Usually, n chess, you have to manuever a great deal, play on for a long time, then get the opposing king out of the square to promote a pawn. No longer true in Gothic, in fact, you can even sac a piece to force the king to recapture, getting him into the rectangular area outside of the square, then you can promote at will.
