My bros game was really cool we were trapped in a mansion with a goblet that cause random magical effects ever so often, the effects were very different. for example one time we were investigating a room when suddenly the floor turned to quicksand. I got to talk a dragon out of eating most of us in the ballroom, and the foyer turned into a jungle. It was a very fun game where you never knew what was going to happen at anytime.
When I got a turn I created a story about an old ancient being of power who had his eye stolen. The players got the gem and it was cursed until it was returned to the being. The cool thing about playing with totally new players is you can draw from successful games of the past and its all new to them. I used some of the better situations from my regular gaming group with them and has a really good time
