This game is insanely linear. U do not need a complete walkthrough. On top of that the world gets generated randomly, so walkthrougs r really tough to do.
Hint: On your map little stars resemble the current quest goal. If u press 'Q' u may chose which quests u want to use that star.

This walkthrough may be completed one day: torchlight.wikia.com/wiki/Torchlight_II_walkthrough
But it is very simplistic due to the linear nature of the game.
Thanks
What I keep doing is totally getting lost, I see the stars and have no problems there, but then since I cannot find my way around most of the time I just repeat things, which is silly. Thanks again so much, appreciate it
