I would personally value it around mid x,xxx. The fact the .net is in use is a bonus.

I feel mid XXXX - high XXXX in 2017, and maybe more - I can imagine 20k for it too in future. It can happen that big end user will approach you in upcoming years, as this is a very good name for VR experience/adventures. I would keep the name and ask for a lot of money for this one.
