Ok, so I think we talked about the genre long enough. And by genre I must specify that I'm only talking about the genre as it is explained in my first post.
For the rest, such as the Era and the other ideas; I will create their own threads for discussion. Or if the author of these ideas want to, they can create a thread themselves as it might be simpler. Everyone can open threads here anyway.

here's the list of genre we have so far, just correct me if I forget one of them:

Genre:
High fantasy/heroic fantasy (high magic)
mid fantasy (usually mid magic)
low fantasy (low magic)
science fantasy (variable amount of magic)
steampunk (magic possible)
alternate history (no magic)
science fiction (no magic)
post apocalyptic (usually no magic)

I've associated all the genre with a corresponding level of magic. I will make a new thread about magic so we can discuss that subject.
I will wait a couple of days and if everybody is happy with the list, I will open a poll.
