We consider STO to be "Soft Canon". We do go through an approval process with CBS, however, the story we are choosing to tell does not necessarily have an affect on anything outside of this game.
We strive to provide you all with the best Trek Experience possible, and we feel that in order to do that, it makes the most sense to be soft canon. This allows us a greater degree of flexibility in our story telling, and allows you to experience things which could not be if we were to adhere strictly to canon.
This doesn't mean that we don't try our hardest to adhere to the canon provided by the films, television shows, and comics, which are considered canon. However, as the story unfolds in other mediums, the story we are telling may, or may not, have any sway over things to come.
That's all I needed to hear. Thanks for responding.
Another thing that makes canon a little confusing. Gene R. himself had a habit of decanonizing things. He didn't like the way the animated series turned out, so he proclaimed that it was not canon. He also didn't like a lot of the movies. So he didn't much consider them canon either. And – okay, I'm really going to scare you with this one – after he got TNG going, he... well... he sort of decided that some of The Original Series wasn't canon either. I had a discussion with him once, where I cited a couple things that were very clearly canon in The Original Series, and he told me he didn't think that way anymore, and that he now thought of TNG as canon wherever there was conflict between the two. He admitted it was revisionist thinking, but so be it. — Paula Block, VCP Senior Director of Licensed Publishing, December 2005
