Second Life is a FREE 3D online virtual world where people can create an avatar and can interact with other avatars. You can build anything you want, go anywhere you want in a virtual cloud that does not have any physical limits. There are no predefined rules or goals. You create your own goals. If you get bored with your avatar you can change it to another one and play with a new persona. The only thing you cannot do is to hurt other avatars, steal from them, or violate their personal space.
Gameplay
The game doesn't really have a final goal, you just hang out with other players, chat, go to parties, watch live music, do whatever you want. If you think about it, this is basically the dream of every gamer who has ever played an MMO.
The game is free to play, but there is a cash store where you can buy clothes, accessories, and other things with real money. All the items in the store are also available for free. You can also earn Linden dollars by participating in the content, and use them to buy things in the store. The game also has a premium currency called "snap" that you can buy with real money, which is basically just a way to buy Linden dollars.
I really love this game. It is an awesome experience to be able to hang out with other people from all over the world and relax
Graphics
Graphics in the game are not very realistic but they are still 3D and look great. I think that they have to choose if they want to make it realistic or cartoonish.
Second Life has a lot of potential and I hope that it will continue to grow.
Replayability
Second Life is an MMORPG, so it has high replayability. The game has a lot of game content, a diverse community and it is easy to make new friends. The user interface is a bit difficult to use, but if you learn how to use it, then it is very easy to do things in Second Life. The game has many options for users to customize their experience. There are many different types of activities to do in Second Life. You can build your own objects, interact with the environment, customize your avatar, have fun with others, make friends, go to school, go to work, go shopping, roleplay, etc.
