Thank you all, guys!
MistbornDave, as Dreamerstreamer pointed out, I was looking for something to play with my players without nothing more in mind that getting used to the system, letting them try combat, rolling some dices... That kind of "small adventure". I mean something that can be played on just a session, and then start thinking about my own stories. I always loved to create my own, and I have been doing for a while (Since 4th edition of "Stormbringer", the ICE Lord of the Rings, that kind of games), but as I said, for beggining I prefer something "premade".
I know I need to read it right now, but this week is... Well, nightmarish. And for the players, well, that is another nightmare. One of them has readed only "The Final empire". Another two have readed the original trilogy. I would like more playing in AoL era, but since noone of them has readed (They only read in spanish, and it's still a month or two until it is released) I would need to play in an earlier setting. Probably before "The Final Empire" events, but again, I need to be cautious whit spoilers with the one that has not readed the whole trilogy. And maybe another player, who has not started reading Mistborn, will show up. That is another of my concerns, playing without spoilers, you know
And haven't talked with my players about an actual play, they think I still not have the book, so it will be kind of (big) surprise when they see it
Are you from Spain too? Maybe we can share thoughts when I start playing these.
