I'm a huge fan of the Classic Client. Over the years, I've tried others. The only good things I felt 3rd Dawn's client had going for it were the new emotes, KR was a step in the right direction, but didn't have the dev support needed, and EC still feels a bit... alien.
But then I came across an article from the middle of last year. You may have seen it - I certainly hadn't. It's a sandbox, the person building it is purely doing it for a sense of achievement and a love of UO. It's not playable. But, it got me wondering what UO could look like with a pair of VR goggles on, and a rebuilt-for-purpose Britannia. Have a look. You won't ask for those few minutes of your life back, I promise.
