Following the release of Torchlight II, Travis Baldree and Erich Schaefer left Runic Games to start their own studio, Double Damage Games and created Rebel Galaxy.
When Baldree and Erich left, the company was forced to cancel the game they were working on and lay off several staff and in the aftermath, they changed their focus to Hob. In 2016, Max Schaefer departed as well who founded Echtra under Perfect World and is currently developing Torchlight Frontiers.
Basically Runic may as well be Echtra Games since it contains several of the former Runic and Blizzard North devs.
And do people honestly click for each attack in these games? You could almost always click on an enemy and hold the button down and your character would continuously attack that enemy until it is dead or you released the button to do something else.
