Basically, it's a Monster Hunter RPG. Not based on the Monster Hunter Series, just a similar idea. Fantasy world which I'll explain more of if there's enough interest. But let me get this out of the way.

The RPG Elements Are:

Currency - The 'party' will have a set amount of money to begin with. Every job you take on (AKA every monster you hunt) will earn you money. Everything you need will cost money. A place to stay, food and drink. You want to go out and party, it'll cost you. You want to buy potions, have your equipment repaired, all that stuff, it will again, cost money. But most things aren't required. It will just affect how you RP. If you don't repair your gear, you as the writer should understand that your character is walking around with broken armor or whatever. Or if you slept outside on the ground instead of in a tavern... you're going to probably be in a lot of pain.

Upgrades - You can upgrade things in your life that will grant you the ability to save money, or make more money. For example, staying at a tavern every time you're not on a job will cost a lot more money than actually having a house to live in. (Rent isn't a thing for owned houses so yeah.) Likewise you can't hunt certain monsters without a boat or an airship, both of which are very expensive purchases, but you can see how they are a form of progression within the RP.

Stats - Your characters will have stats, however these stats aren't strength, intellect, whatever. These stats revolve around crafts and the like. Gathering, Alchemy, Engineering, all of these things have specific purposes such as brewing your own potions, or using supplies available to you to create some form of siege equipment that can be better used to take down a monster. This isn't a full tabletop, so don't expect like, roll checks or anything. It's basically just "I want to do a thing" "You fail because your character is socially inept"

So yeah you can think of this all like a game of sorts, but you should also be thinking about character progression and development, not just playing it like an RPG where the end goal is to become rich. 

Basis of the story is that four characters come together to form a new monster hunting guild. It's just the four of them, and so you can only start off taking pretty simple jobs. Build a name for yourself, get more equipment to take on larger threats, and eventually even start taking on new members of the guild, as much larger threats won't be able to be handled by just four people, and you will need side NPCs to help you.

It's undecided if I'll be playing a hunter myself, or just sort of like GMing the whole deal. 

Anyways, any questions or whatnot are welcome, I'm not sure if I've made the whole thing clear.
