I have only spent about 26 hours in this game at the time of writing, and I adore it. There is so much potential that I can't wait to see, and I figured I'd throw in my metaphorical hat and make some hopeful suggestions!
Immersion in this game is one of it's best points (in my opinion), so I'll start there!
Beasts and their Burden
I've seen so many suggestions of horses and mounts, which is all well and good, but what about the Ox? I think inventory management being gated by progress keeps people engaged and motivated to find the next best thing, so rather then just "more backpack upgrades", I suggest carts, wagons, and carriages for these new chonky bison beasts!
Carts and Beasts of burden can lead to much more thrilling "wild west"-esque expeditions, taking planning, sorting, animal feed, and supplies! It makes carrying tons of rock for that castle all the way from the mines a much easier task. You can (potentially) choose between horses, rams, or Ox to alter speed, offroad handling, and capacity! And most importantly- Cart construction, taming and harnessing Ox or Horses, and accessories can be expensive to build!
Immersive Foods
Not a new idea, I know. But more recipes (post cooking included) would be a welcome change!
Jams and Jellies being spreadable on toast!
Sugars/Maple syrups with Calories but no nutritional value.
Using fat as oils to render fried foods.
Honey/Maple Candies for quick cheap caloric boost!
Not to mention methods!
Small campfire grills could be easily constructed with a slightly modified metal plate recipe, and could grill multiple foods at a time!
Adobe Ovens could yield artisan breads, or simply be more fuel efficient/faster while maintaining a lower max temperature.
Smoked Jerky could be treated after salting the meats for extra effective road rations (for those long Cart Expeditions!).
Mason Jar Preservation- Constructed from glass and a wax cork with all the benefits of fully sealed crocks, without the expended fats/wax!
Tools of the Trade
Tools and their durability have had a lot of suggestions too! many suggest sharpening or reforging to regain durability, but my focus is on the actual maximum number to begin with!
Sturdy Handles- No more random bush sticks jammed in your fancy axe! just a few planks of wood and some sawing yields you a Sturdy Handle for your tools! Made from tougher stuff and sure to boost your durability... by a bit.
Ornate Handles- Made from much more expensive materials, taking the time to make such a commitment to your tool comes with it's benefits. Greatly Improved durability and a slight increase to damage with all that extra weight!
Bindings- Made from plant fiber, hide, linens, and leather (And rising in durability respectively) These lashings will help keep your tool-head on it's shaft where it belongs, and not thrown off over your shoulder mid swing.
I hope any of these were helpful, inspirational, or at the least entertaining to whoever reads!
Thank you!
