(Im going to be bad at wording this so bear with it.}
So your current road map is more like a blank slate of SoonTMs and im sure it unsettles many of the current soon to be user base. A better way to both show progress and ease the fire throwing trolls from hell would be to do something similar to this modding community roadmap
https://www.rustyrevolution.org/roadmap.php . they give their progress quantity by percentage. Granted they are reviving a game rather than making a new one so the percent thing is much more viable of a method for them that still doesnt mean Intrepid couldnt do something similar. It would also help out the team with a more fluid state of work. ok im stuck at this point for awhile and its at 68 ish percent. lets jump over here at 41 percent and see if i cant work on that to refresh my mind and make some progress on that. i know its not a great way to describe it but i do hope you understand on what i mean. you can also set markers at these percents like at 75% of say graphics release batch of cosmetic pictures or 75% of node do node diary for node type and so on. Thanks for coming to my Ted Talk. Ill better refine this thread as time passes so it can be better read by all. tomorrow.
