We bought Torchlight 2 for everyone in our family, and we play it together sometimes on Family Game Night through our local Ethernet. (We wired all the rooms in our house with Ethernet, so we have our own network.) The game is a fun point-and-click adventure that takes up where Torchlight left off. To begin a new game, you pick your character, either a berserker, an embermage, an outlander, or an engineer. You can choose to be either gender, with a plethora of choices for hair style, hair color, and face. Then you pick and name a pet. Pets are important, because you can send your pet back to town to sell items you don't want and buy items you do want, like healing potions.
You start by getting a quest to go to a nearby town. The beginning leg of the journey is rather easy, regardless of difficulty, allowing the player to learn the interface as he goes. Once in town, you get more quests and uncover more of the storyline.
I have played the main quest to completion three times, as an embermage, outlander, and engineer. Torchlight 2 contains lots of side quests, a hidden quest, and a lot of entertaining options along the way.
For people worried about privacy or safety, you can play the game all the way through by yourself. You do not need to log into a network. Torchlight 2 also has a local co-op option, with is how I play with my family. Again, only known people can (hopefully) access your local network.
While the game is mainly played for fun, if you play with others, you learn how to work as a group. Also, figuring out which weapons or armor to use requires some math knowledge.
Overall, I give Torchlight 2 a five-star rating.
