Offline mode was why I was willing to not only spend a lot of money on the kickstarter campaign, but to spend even more money as things got rolling. I really do like the online mode of play, but detest games that *require* me to always be online whenever and every single time I want to play it. I have seen it said, "there will most definitely be an offline mode" over and over throughout the last couple years that this project has been going, as recently as 5 days ago! If it is a technical issue, then take some more time and fix it, I am willing to patiently wait. I really look forward to being able to land on planets, but I am willing to wait for that because I know, as we have been told, it will be coming.
But to say, there will be an offline mode for over 2 years, and then at the last minute say something like 'opps, my bad, it won't be there', is a *HUGE* slap in the face to all of us that took you at your word! So, what else can we expect to have changed at the last moment? The promise that we can land on planets changed? What else are we going to have to second guess now that you are starting to show you will not keep your promises? Can we believe anything you say now?
If it will take some more time to provide some kind of server, with limited functionality so we don't expose your precious secrets (what were you thinking when you promised offline mode to begin with?!), then do it, and say so. I am willing to wait. I have spent a lot of money on this, and really hope my investment isn't going to be met with half truths and misstatements.
