If you could figure out how to leave the god forsaken noob fest of "Miramare" which is the lag infested hangout for noobs you'd actually find some interesting stuff. I'm sure you had the blue jeans, white T-shirt, and poofy hair thing going on for ya eh? Take the tutorial, look at the top right of your screen, search for sandbox, teleport there, and then learn your crap. If you think it's just about socializing, you never took the time to explore it, contact "Nalrune Ansar" that's me, I'll guide you all through Second Life and show you what experiences can be fun, they have PvP places ya know? Where you can punch+kick the crap out of each other with custom animations that you can even make yourself, I'm an animator, a builder, and I make textures. Did I mention you can make real money off Second Life using those Linden Dollars.
I forgot to mention, there's swords, katanas, throwing knives, guns, cannons, C4, laser guns, light sabers, anything imaginable. There's bow and arrow, RPG games within Second Life, flaming arrows, ice arrows, spells, teleportation, laser eyes, anything imaginable I'm telling you. You can even make your own stuff!!! Want to make a watermelon launcher? How about a spitball and straw? Want to join a Japanese community where role-playing is a requirement... yeah do it.... and they might have enemies such as the Nords, (who are real players) that will come and assault, raid, and pillage you and your fellow friends, and home. Want to join a successful business or work for the government and have a shot at a RL career, it's all here in Second Life, I can go on and on, there's vampires, werewolves... there's even the Matrix for crying out loud, I'm not sure if there's slow-motion, I'll have to look that up. Once you get to the sandbox, figure out how to IM people, send "Nalrune Ansar" (ME) an Instant Message, and I'll fill you in on the basics and whatever.
