Stray too far from existing fluff will risk alienating the current players ( who should be grateful the game is still alive)
Should I be grateful? To whom? That sounds a bit too consumerist and slaverish in my opinion. The game is alive not because someone bought it and maybe, someday, and I don't know when, will release something that may look like it in that direction. I, along with another couple of players from my club and another friendly club, continue to support the game as it is, not for the fluff, but for the models and mechanics. The fluff I invent for myself, as an example, is my own completely, through knowledge of history, with knowledge of the classical literature on the topic (think Jules Verne - Robur series, and Herbert Wells) with a little droplet of own imagination added - in short, I do not care what kind of fluff is created by whom, I just like the mechanics as it were, so I don't simply consume ready-made pies and pastries, I like to cook for myself the story as well. If warcradle changes a whole lot of it's mechanics (really I don't expect changes for the best when they happen, from experiences, so please excuse my pessimist tone here), then I would not worry - we still have the old game rules (and majorly thanks to Ruckdog for doing up a G-drive full of these documents) and the new things can be completely ignored. In addition, I am not sure these guys will make the rules available as free downloads... but this matter we shall see, they may, and I may be wrong....
In any case though, these rules have also seen adaptations to historical scenes, like pre-dreadnought era naval battles, and actually being my little "pet-project" of a sort, so I am in it too.
So to cut it short, the game is a relic, like most other things that have died in the past, but it life continues on as people who liked the game will support it in various means, disregarding what the wholesale system has got to say on such matters....
