What an awesome video! I work as a web designer and I was very inspired by the user interface! A very good layout! The personality traits seems a bit complex. I found it interesting as it becomes a part of the back story of the character. Having sliders for fine tuning the look will be helpful.
Do please continue creating videos as it gives a totally different overview compared to some screenshots and text.
Suggestion for a video could be how characters and NPC's interact through dialog, bartering, battle, romance and whatever else. How characters and NPC's are influenced by various factors such as personality background, equipment worn, charisma, personal dialog history, quests etc.
Another video could focus on how battle works. Users of magic have different spells they can cast. What about variation for characters/NPC's that use distance and melee attacks. Fighting styles for bows/crossbows/throwing grenades etc and close up fighting. Such as normal, defense, block, aggressive, etc styles. I am thinking a light version of fighting styles would be nice to have included.
(I added the above comment here in addition to directly as a comment on Kickstarter. As it feels more personal in this space.)
