I actually invested a small amount in MANA, November 2017, but not enough to buy a parcel of land. It looks a really exciting project and wish I'd had enough funds at the time to join the auction.

I sold my MANA at a slight loss after the pull back started (to free up funds to invest in Steem), but MANA has rallied quite nicely I think from its lows.

As far as I was aware, they were building their virtual city in stages, with more layers of detail & functionality being added over time - although I'm not sure whether it's actually a "place you can visit" yet, even for land-owners.

It's a project I'll be keeping my eye on in future, but I don't see personal VR taking off for a while yet (until the headsets become contact lenses & we'll all happily use them).
