... can someone tell me the reason why he/she is actually playing this game? i don´t get the point??^^
please answer thank you

What is the point of New York City, NY? Or Paris, France? I mean, why would anybody visit those places? Sounds silly, doesn't it? It's much more accurate to think of Second Life as a "Place", one that can be visited by people from all over the world, for merely the cost of Internet access, rather than a plane ticket and all the hassles of real-world travel.
Second Life is not "a game". It can be used to play various games, from roleplaying to hide and seek, yes. But that doesn't make the whole of SL "Just a game". Is your computer "A game"? No. In is a tool that enables you to play games, among many other tasks. Likewise, Second Life is a communications tool that may look somewhat like a game, and can be used to play some types of games, but it's really much more than that.
Real world Universities have campuses in this virtual world, and teach classes here.
People meet with friends and make new friends here, regardless of where they live in reality. My best friend in SL, for example, lives in another country, thousands of miles from my home town. Yet we share a castle together in SL, a castle that I built, and whose land is paid for by work that I do inside second life...
I happen to be one of the small minority of people in Second Life who manages to run a business and make a profit in this virtual world. I work about 20 hours a week here, after putting in a full work week in a real-world job. My SL business efforts earn me less per hour, on average, than if I was flipping burgers as a second job. But it is FUN, for me, I can do it from my home, and I set my own pace, and what I do manage to earn here helps buy some nice things once in a while for my family. But MOST people in SL do not make a profit here, that ever ends up in their real-world bank account
Second Life is a medium of artistic expression, for some. It has some amazing capabilities in that regard. A lot of SL business owners create things because they like to, and sell them because it helps reduce their expenses here. If they occasionally make a profit, that's a bonus, but not expected.
Is there crime here? Yes, just as there is in any Human society. Criminals won't politely stay away just because it is a Virtual world. Not if they think they can scam somebody out of their credit card information, or profit by stealing someone else's work, or... And just like any other segment of society, you have very nice people and very nasty people, and everything in between.
But that is the core point. It's people... Every avatar you see walking around is controlled by a person, and not some pre-programmed game resource. (Yes, some avatars are controlled by programs. We call those "bots". But they are still owned and programmed by individual Players, for their own purposes.). If you play a "Game", you're usually pitting yourself against the game designer's pre-programmed resources. You may be alone, or you may be networked and playing with friends, but most of the "opposition" is just computer code. In Second Life, the vast majority of the people who interact with you are just that, real people, sitting at a keyboard somewhere. With all the good, or bad, that this implies.
