A few questions while I work on my CS:

1 Will the players know eachother IRL as well or are they from all over the world?
2 Do the players all have usernames and if so where do I put it in the CS?
3 Do we have a set age limit?
4 What does each stat do? Some things like Strength and Stamina are easy, but what is the difference between Wisdom and Intelligence and how is Luck a factor?
5 How do guns come into the idea? They would probably exist within the world but how do they work and does stats have anything to do with how they handle/which ones you can('t) use?
