There are missions but they’re different. You need to buy a kit first that’ll let you do a certain kind of mission, for example a kit to find special herbs that you bring to a particular character.

Money is more scarce and it is split between “regular” money and gold. Gold gets you good stuff like fancy horses or outfits or kits, but it is rare in the game, unless you pay real money for it.

All that said, there are a lot of people modding and playing online can be quite chaotic, with random objects becoming attached to you, animals spawning, massive explosions, invincible people, etc. But some people are also benevolent and will protect you, especially if you have a low level, and may even gift you stuff.

Anyway, I’d recommend you give it a shot, it’s a way to play with the characters and places you know but in a different way.
