As I said, I don't get it - why do you need canon in an rpg? What is the added value for me in Mongoose telling me what tech I can or can't use in my games? Charted Space is malleable enough to survive the inclusion or removal of all kinds of technical gadgets.
You
don't need canon in an RPG. You need canon in a S
etting.
Charted Space is a
Setting.
Middle Earth is a
setting. I do not want a Game Publishing company who has publication rights to the
Middle Earth Legendarium for their RPG Game to introduce Dwarves with Springfield Rifles and Kzinti in "
Eastern" or "
Far Southern Middle Earth" simply because they can use the excuse that we have never really seen what is there. Nor do I want Phasers and Photon Torpedoes being introduced to a
Star Wars game universe. It ruins the flavor of the setting and opens the bag of unintended consequences.
It is an issue of respect for the setting.
Charted Space is a
setting, just as
Middle Earth is a
setting, or Herbert's
Dune Imperium, or the
Star Trek Federation, or any world/universe created/imagined by your favorite fantasy/sci-fi author.
Furthermore, as the above-mentioned settings,
Charted Space was an existing setting with a long history and flavor and feel
inherited from someone else. It should not be abused. If new items/ideas can be introduced that have been thought through in terms of overall setting-consequences that fit with the feel and/or do not alter the flavor, that is great. Let the setting grow
appropriately.
But if items are promoted, modified, detailed or introduced that do not fit with the feel of the
Charted Space setting (or
2300AD, or
any other setting that they support for that matter) - or are at least questionable - , then they should be noted as such in the description or in a header, or be listed in a section of alternative ideas or technologies (relative to
Charted Space, et al, that is) or otherwise be clearly marked as such for the sake of clarity (and for those who are less familiar overall with the setting, especially content writers and newer players who wish to use the historic published setting).
I have no problem with all kinds of things being made available for individual GMs to use and/or introduce in their campaigns. Individual players and GMs can do whatever they want in their own campaigns with their own gaming groups, but they should at least be provided with a clear representation of what a given
setting was intended to be like (whether
Charted Space or something else), and what was intended to be in it, and what was not. Then they can decide what they want to do with it - use it as originally portrayed, tweak it, alter it, or radically deviate from it as they choose.
