Introduction: Right now, absolutely NO ONE uses wooden weapons. NO ONE. Usually, they will use a Wooden Pick to start the game, and maybe a Wooden Hoe, but no on ever uses the Wooden Sword.
Proposal: Wooden weapons will now deal but one point of damage (and will be renamed Training Weapons), and will be replaced by Stone in terms of damage. Stone, in turn, will be replaced by Flint. This makes Stone weapons a starter weapon, and makes your flint a little more valuable early on.
Extra: Daggers, Spears, Pikes, Axes, and Hammers will also be added to Wood, Stone, and Flint. If possible, also Gold and Diamond, as I hate having to create Special Items using only swords.
Notice: This post does not apply to tools. They remain the same, as who ever heard of flint smashing through iron ore?
Edit: Adjusted title to make it more specific. ~Alte
