Virtual Tours/Worlds and where i'd go.

I never knew there was such a thing online until Professor Fry discussed this in class. But what an awesome racket to get in on if you have the capabilities to be a host of one of these sites or the know how to create the technology. The future can only look brighter for those entrepreneurs. I can see this taking off into something as addicting as the online games, except better. I'm sure, however, it will come at a cost. Someone will be up in arms about what ills it will be doing to society. But that's a whole other subject.
So who will use these virtual worlds as technology sits today? Besides the obvious gamers, people who could never afford to take vacations, people who want to see the places before they actually take a vacation there, school kids doing a report on another country, and then there is Me... I know for sure i will never go to places like Australia, or Japan, maybe never Europe. I have a few other places I'd like to go first and those seem to be a challenge to schedule in and afford. So if you can't see it in the flesh, whats the next best thing? A virtual world. Yeah! I bet there are ways in which the entire family could get in on that too.
I can't wait for the virtual world to be interactive, when i can do a virtual visit that feels like i'm on the Starship Enterprise or a new galactic federation world, i am so there! Even better, visit the places in Star Wars like tatooinne, maybe i could throw my Ex in to the Sarlac. (oops better not, i might get in trouble for that!). But i could go to Yavin 4 and train to be a Jedi Knight or do the Kessle Run in 12 parsecs with Han Solo and Chewie. THAT would be Awesome! And yes, I know there are games that i could already be playing that do those things, and strangely enough i haven't had time to mess with them. Too complicated, so depending on how complicated the virtual world is, i may not have time for that either. But i can only imagine, that with time i won't have to take several lifetimes killing myself in games & running out of life to figure out how to use the dumb remote control buttons in combinations that do things as simple as jump or changing a weapon!
