Second Life is a free-to-play casual simulation MMO developed by Linden Lab for PC, Mac, and Linux. Second Life does not have classes, any particular objectives, or any traditional MMORPG mechanics. Instead, the main draw of Second Life is the enabling of user creativity, avatar customization, and socializing (often through roleplaying). The game is a massive, sandbox-like environment where other residents (players) have created a majority of the game's content and zones you can travel
to. Those looking for a game they can truly get lost in will find themselves right at home in Second Life's practically limitless world.
Business Model: Free to Play
Microtransactions: Yes - See Marketplaces in Features below.
Roleplay: Second Life gives you the chance to truly become whoever you want, whether it be a pirate, club owner, zombie fighter, or anything else entirely!
Creation: Creation is a key component of Second Life! If you can imagine it, you can create it. Animations, scripting software, 3D models, clothing, vehicles, and skin textures are just the beginning of what you have the tools to whip up.
Marketplaces: Sell your creations for Lindens in one of many marketplaces throughout the world. These Lindens hold a real world value and can be exchanged for US Dollars on the game's official website.
