Any fears that Torchlight 2 might suffer from its proximity to Diablo 3 or sequel fatigue from the first game can be put to rest. The game has managed to top a million sales after approximately three months on the market--a feat its predecessor only reached after a year and a half, even with the advantage of appearing on two platforms.
Torchlight 2 was released in September and reached the milestone by the end of December. By contrast, the original was released in October 2009, followed by the Xbox 360 version in March of 2011, and had a slow snowball effect to a million sales in July. While the first game was popular on console, Runic has been frank about the reasons Torchlight 2 isn't destined for the platform.
