The game’s name is Second Life, and yes, its linux client is the most hassle-free version I’ve ever dealt with. Simply download the package, extract and run the game. There’s no compile-and-install steps at all! If you are running on alsa sound system, your have a video card better than geforce2, then you’ll have no problem running this game. Make sure you’ve installed the nvidia driver like I did, and if you are on ATI cards, fglrx is needed for 3d performance.
