Many thanks for your support and advice.
If it turns out that TTOW has enough interest in the survey that I go forward with the Kickstarter then I'll probably include a free copy of TROS at around one of the low-mid level tiers (around £20 ish) since the game is over a year old now and I imagine many people will already have a copy.
Thank you for the insight on 'asks'. I'll certainly be aware now and make sure I've a system in place to balance my work with my update/social media obligations when and if I have a Kickstarter up and running, and of course, beyond. I'll take a look at the blog you mentioned and see how they do things for some inspiration ^_^
And, yes, I was thinking fortnightly to monthly updates for any backers, should a Kickstarter be successful. I would want to keep in regular contact with people who have put their trust in me and I know that, when it comes to delays of any short, not knowing the circumstances is the worst part.
Thanks again for your feedback ^_^
