Active worlds was made back when 400 Megaherz was a fast computer. It has been updated but you can all ways lower the view distance and other ways if it lags out. I was a member for a few years but not right now. Active worlds has a wide range of worlds that run from cute and kid safe to very werid and not even safe for some grown up's it's so werid heeh They have ppl called peacekeepers who keep a eye on the open worlds but less so on the private ones. You can create whole towns and there are those who use modeling programs to make new objects. As for talking to other on it the talk ranges from the silly to deep to quick were's my mute button heeh. You might like it than again you might go running screaming and delete it right away. You can try it no cost but a membership cost about 60 usd a year last time i checked. I had lots of fun using it.
