It seems that you played this kingdom: Cellar, Menagerie, Militia, Moneylender, Smithy, Tournament, Festival, Harvest, Horn of Plenty, Hunting Party, and were disappointed with speed at which you bought provinces using hunting parties, militia, and treasure. Firstly, you played militia 8 times in the last 14 turns, which is a big benefit. That makes it far better than smithy+silver. Secondly you can add cellars, tournament, moneylender, festival, and horn of plenty to the hunting party deck in this kingdom and make a very exciting deck. Those cards might not be present in every kingdom but there usually is something else productive.
It's also worth remembering that big money strategies are often not decisive. A better strategy might only notch up a 65%-35% win rate If you lose a game you might be seeing one of the 35%.
