Same difference between a Brit, an American and a Scot. They all speak the same language (accents aside), but the culture of each will be rather different.
Reste a voir, Moa, reste a voir...
Part of me wonders how they'll pull it off, the rest of me wonders if they'll manage to survive long enough to give rise to a new king of technological support/game medium I have heard one of the bosses at Asmodee talk about (ie.: yeah, the major players are looking into ways to head in this direction, so get ready guys, this is only the beginning). And all of me hopes it'll be a wonderful game and a cool thing to play.
