Just found out about wander.
It seems like a fairly interesting concept. Reminds me a lot of Endless Forest, which is one of my most memorable MMOs. Of course, EF is fairly old now and is smaller in scope. But it also has the peaceful, collaborative nature that Wander is aiming for.
I'm wondering if Wander will allow you to talk to other players (TEF didn't allow this, you could only use body language of your deer to communicate). I guess I'll need to read up more on it. There's about 28 minutes (or maybe more) of interviews to watch, so I guess I'll do that after I've posted this thread.
