I rarely visit Inworldz, even though I've had an avatar there nearly as long as in Second Life.
Truth be told, I have a bias against Inworldz, since my first experiences there were so poor. When I first rezzed in, I could walk hardly walk 10 steps without sinking into the ground and getting stuck. And unfortunately, it wasn't only me … later I discovered that some sims would set out dance and other pose balls at intervals to help you get unstuck.
I’ll skip over the problems with finding shops to buy some decent bits and pieces to create an avatar. But the quality of many builds was also less than impressive, so there was little to draw me back. I couldn't understand why anyone went there, other than it seemed most Inworlders and those that talked it up had a huge hate on for SL.
Builds are better, graphics and textures are better and it no longer feels like walking through mud to get around. As a matter of fact, some of the builds in the sailing area I visited were easily the equal of SL.
But there is still the problem of people. Perhaps this new infusion of stores and creators will draw some in, but frankly, going to a VW where there is only 200 or so people in world time feels a bit desolate.
So, the upshot is I won’t be leaving Second Life for Inworldz, though I may spend a little more time there exploring. Now, if I could only find a nice quality sailboat there….
