I just found out that LL officially (and quietly) gave up on the idea of SL for Oculus Rift way back when they announced beta release of Sansar. Guess I shoulda figured it out, but I'm kinda disappointed.
I tried Sansar on the PC - meh. I know its been discussed to death so I wont go into specifics.
I bought Oculus Go. Its awesome, amazing, incredible, for only $200, blahblah ... and a purchase I regret. After a couplea days it feels like 'been there, done that'. I've felt my stomach lurch on a few impossible coasters, come face to face with deep sea fish, watched short little videos, been drooled on by T.Rex ... now what? The socialization aspects are bland and cartoonish. Yeah, "my house" is 3-D but it looks like the stuff I found on SL in 2004 and there is nothing that can approach Calas Galadhon (for example) in terms of dynamic immersion, emphasis on 'dynamic'. The things I can see may possess a bit more positional depth but thhey aren't any prettier and they're far more emotionally shallow IMO. In any social space I can find (there are a selection of completely unrelated/unconnected choices) the avatars look like Weebles, the movement and interaction is clunky at best, and there is no ... connection. There is no mainland to travel, there is no "IM the creator of this if you have a question". If I could just hold down a damned button to walk that'd be nice. Instead I have to stroke the touchpad with my thumb for each small movement (in clumsy intervals). What I recall from Sansar on the PC it seemed marginally more fluid that any social space I've found on Go yet. If Sansar becomes accessible on Go I'll have a look, but not very optimistically.
I don't like FPS games. If I did I might be enjoying Oculus Go. I can use Go to access Netflix and *shudder* Facebook... with less alacrity than on my PC ... but hey, I do it in total darkness and turn my head to see stuff at my virtual sides! ! *yawn*. If the content had any depth I wouldn't give a damn whats at my virtual side. Some of the UI elements I first encountered on Sansar are found here, which kinda explains their origins and presence on Sansar I suppose.
More style-over-substance. I feel stupid for having spent $200 for a coaster ride and some dinosaur spit.
