Torchlight is free to download and keep indefinitely on Arc, Perfect World Entertainment's digital storefront/client.

Torchlight 2 isn't free, but it is 75 per cent off until 30th November as well, making it €4.75 rather than its usual €18.99.
Eurogamer contributor Alec Meer called Runic Games' dungeon-crawler "the best Diablolike since Diablo 2," in his Torchlight review back in the day.
Our Chris Donlan loved its sequel as well. In his Torchlight 2 review he called it "a colourful, heartfelt and well-judged spin on one of the most reliably engrossing genres knocking around."
