I believe it would be an interesting concept to explore in this game, going through the act of finding, forging, chiseling, experimenting with, and finally maintaining and using classical, or ye-olde firearms from the early era of humanity!
Essentially, I see this as a new path of long range combat, which could even go so far as to have its own tree of skills and places of use, with skills that could assist in the admittedly slow reload times of yesteryear’s muskets and powder pistols, to giving you the ability to dual wield all together! Being as creative as one can be in the respective tales of a players choosing, adventurers could search the land for recipes of special ammunition that could find special value against particular prey, like explosive rounds for confronting Turabadas at long range, or a dragon’s breath buck round that could assist in clearing aggressive forests of Goteras via a fiery grave. Exploration would also net you moulds of special barrels capable of holding different calibers and ammunition, triggers, and firing mechanics like pumps or revolver style hammers would also be quite a satisfying find! That’s before even mentioning the possibilities of gunsmithing, finding out what barrels work with which grips, creating every bullet by hand, using better material for better efficiency and a reduced change of weapon failure or outright destruction (like a barrel eventually exploding after extended use or weakness of metal), and the idea of creating your own special lead slinging abomination with the creative freedom of each and every self proclaimed gunslinger!
Personal twist (optional)
Honestly I adore this game, the team working on it, and the aspirations of that team, and I can totally see this kind of expansion coming out for it, with its physics-based nature and focus on crafting and exploration, I just cant see how this kind of expansion wouldn’t be an enjoyable experience, being able to build a long range musket or repeater piece by piece, using different metals for less warping on a barrel to maintain good accuracy at long ranges, or going into a cave and fanning a few rounds into a crystal wyrm that sprouts a bit too close, panicking as I run out of bullets or there’s a malfunction that causes my gun to jam, and just imagine the outfits!!!
Anyways, that’s my two cents in that matter, if anyone has read this far, thank you for taking the time out of your day to witness my idea in all its randomness and incoherence, I hope you have a beautiful day!
