A few suggestions.
- The ability to have and train an apprentice.
- The ability to pin up the instructions somewhere (or have a menu) to streamline the learning curve.
- Weapon customization, i.e. Engravings, Hilts, Different Guard and Blade Designs
- Custom Orders, that payout more. (Pairs with number 3)
- (This is probably the biggest one) The ability to use weapons you make to adventure.
- Crystals can power up weapons (Goes with number 5)
- Weapons have different status effects (Goes with 5 & 6)
New Crafting Ideas
- Small and Large Short and Long Swords (Not really new, just a distinguishment between the two)
- Bows and Different Types of arrows, I.e. Poison, Sharpness (Causes a bleeding effect), Silver (Extra monster damage), Armor Piercing to name a few.
- Shields
- Axes
- Scythes
- Staffs and Staves
- Cestus'
- Gadlings
- Push Daggers
- Whips (Maybe like a small blade on the end to do damage.
- Kanabo
- Halberds
- Flails
- Kunai
- Kusarigami (Had to put these in here they're badass)
That's all I can think of without copying other suggestions I've seen. Love the game by the way. Keep it up. :)
