I just fired up Kaneva. The updating took longer - much longer - than a complete download of SL. There's only a one or two hundred people online , so there can't be too many people downloading the updates. I understand that people go through this process for regular online games but those games have more going for them, for the people that enjoy them, than Kaneva has going for it.
Upon arriving, I was once again struck with the question I always have when I enter Kaneva: What is that door in the apartment for?
Looked around at my picture of Andrew Linden and a Max Monde build, both of which are tiled unpleasantly because you can't adjust the texture scaling, listening to my boombox playing Torley music. The Torley music is nice, so Kaneva has one good thing in it, but it was made by a Second Life employee and put there by a Second Life user.
Then I went around the apartment, bouncing up and down to the Torley music, which gives a glimpse of the cityscape above the ceiling due to a little flaw in the camera system. Went over to the little room in the almost unfurnished apartment and asked myself the second question I ask after entering Kaneva:
What is the little room for?
I listened to my music play for a minute, noting that the bounce rate sort of matched the beat of the Torley music.
I next went to the Mall, the public place where the most people are, and I ran into this:

That's something that wouldn't go over too well in SL.
The Mall reminds me of early SL in a way, people trying the gestures and dances, looking rather primitive and silly, because they don't have much choice of gestures and dances, and they want to do something rather than nothing and that's all they've got. Like doing the old F12 dance used to be.
SL avatars look better than Kaneva to my eye.
Swithched my camera, you can be in third person from behind, like we are in SL, or in Kaneva's version of Mouselook, or - and here Kaneva has SL beat - third person looking at your avatar from the front, like I've been wanting SL to have since Decemeber 22 of 2003. Otherwise though, the camera controls leave much to be desired, like, umm, aiming, tilting, panning, etc.
One thing that I find very effective in conveying a sense of really being in SL is the way the camera bounces around as you move. The camera is anchored to your avatar's pelvis, and that makes the camera move in somewhat the same way that your visual field actually move in RL when you walk around.
Kaneva's camera does not follow that model, it's like a movie camera moving on a meticulously smoothed and oiled track, like the camera in Multiverse. This kind of camera is great for Machinima and I'm sure is fine when you are just playing a game but if the designers have a goal the imparting of a sense that your are your avatar actually in the virtual world or that your spirit at least is in the virtual world, the smooth movement of the camera to me largely ruins the effect. Real bipeds trundling about just don't have the fluid graceful organic eyeball camera movement that Kaneva and other virtual environments I've seen have.
Next thing I notice is people chatting and using the word Rave. Sheesh, what a rotten choice of words to mean "pos rate", the Kaneva folks should have gotten out the thesaurus and used ten or twenty different words in the interface at different places so you don't have to see the world Rave so many times it makes you want to pull your hair out or punch your fist through the monitor or something.
I get these emails from Kaneva with supposed news or links to Kaneva forum posts so I follow them to the company's web site, and it is a mess, not as bad as it used to be, but still, it's hard to tell what to do once you get there. SL's web site is a model of clarity by comparison.
Kaneva's supposed to have some games introduced; I'm not sure if they mean games to use your avatar to play in the 3D world, or if they are gonna be 2D games, which would be fun, but which would not be making real good use of the 3D world, especially in light of the big loading time necessitated by the 3D world format. You can find places with perfectly good free multi-user 2D games with no trouble.
Here I am in Kaneva at the Mall:

That's as much as I can stand to write about Kaneva at the moment. By far the best part of tonight's experience was Torley's music.
