all sweet questions!
1. more of a gravity was the original concept, however i'll add certain elements of sci-fi into it
2. in terms of technology, we are talking similar technology to today, but slightly more advanced. Not seriously... but a good 5-10 years worth of electronics and equipment, perhaps with a slightly more advanced apparel available.
3. When I said lead, I merely meant that was my character job. He worked as a lead on the mission. To be honest, I will just rp normally. My characters job is just to guide and move the story along with plot posts and intervene every now and again.
4. I was thinking anywhere between 1 and 3 paragraphs. I dont like to judge people's writing ability or style. As long as its enough for us to tell and play a good story, im not too fussed. So 1 good paragraph minimum, but apart from that the sky is the limit.
5. I said 5.... but if you want, all 7 of you are in.
