SL is at this stage is very much like the first Nintendo game consoles. I remember, like, six or seven years ago hearing about virtual reality becoming the big thing but it looks as though it has only just begun.
Although it is 2006 and we have a 3D effect, it is slow and flat.
As time moves on and new generations move into existance I would imagine that three or more generations will have to go by before we see this place really take virtual life on.
Sorry to sound disparaging but it seems like that's the reality, to me anyway.
By then though, the characters or avatars will be very lifelike just like the latest nintendo games. Just wish I could start then.
( Just ranting, I got nuthin else to do.)
