What are you buying?
XD Actually, in all seriousness, I'd probably be selling weapons, heal potions, and upgrades, as well as do some forging and attaching spells and such to weapons on the side. And maybe do a rent a mount. And Of course I sell to both sides, I mean why not.
The good guy goes and buys a sword, the bad guy goes and buys a sword. both hurt each other and maybe walk away, then come to me for healing and a more powerful weapon, as well as a mount to go find they guy they're after. I could essentially pay for everything for the rst of my life, my children's lives, and my children's children's lives just on the money I'd be making on two people.
And hten I'd do some minor investing in the whore houses and such. Come on, I'm a business major, I'm designed to make money.
