Second Life
Communication on SL is not too much different from communication in real life, other than you have to type out what you are saying; if you want. And in real life you can’t just jump from BG to Japan, and you can’t fly in real life. Many signs have already been shown to show where you go for games, and where to go for finding stores.
Most logos have some universal relation to what an organization does, many times it is abstracted for the sake of copywright.
Artful designed logos and signs are more memorable. If you like the way a logo looks then you are more likly to remember it and that is the objective for a company, to be known incase they are needed.
Sometimes its hard to see where things are in the distance because it doesn’t load so far or it doesn’t load very fast. So knowing where things are already is really helpful so you don’t wander around forever.
Also sometimes to work a game you have to push something and a lot of the time you dont know where to click a sign could help you know how to work a game.
