If you are looking for Storytelling, I'm using the Chronicles of darkness system to run games. It's easy to handle, I ran games for people who never even played any role-playing games and it went well. I got many ready scenarios and I'm building a world for more than 2 years called Shiner State. Located not on the East Coast, 4h by ferry from New York City, we got a wide array of locations in the State. A big city called Shiner City, small towns (Lonepinetown, Mallentown and Wilmotown), the county, a mountain with a ski resort, etc. I got a Map for all cities and some specific locations, such as the university, all my NPCs are drawn, from the mayor to soldiers, kids, old people, I got all kinds of people with their own stories. The equipment is drawn, so I just give you access to the handout when you own something. I got a draw for almost everything, even vehicles from John's vehicle, an American car producer. I am a professional GM that is just about to launch his paid games. All games come with a custom illustration of your characters and 1 person in his surrounding. I got 4 scenarios, including a zombie one, one where portals open in the city and invade the state and two with the supernatural. However, 6/8 players is an extremely big group, I suggest splitting in two to be more fluid, so everyone can enjoy and play. A zombie scenario could be easier to manage with a so big group, but splitting seems a better idea, in my opinion :) The portal could also make it, but I'm afraid of players waiting if the group split, which usually happens with a group big as that.
