Runic Games' action-RPG Torchlight is free for 48 hours on GOG.com as part of a "#NoDRM" promotion. If you've somehow managed to avoid the game all these years -- impressive work -- you might as well take part. The offer lasts until Thursday, June 20 at 12:59pm GMT. Go get it!
Elsewhere in the sale, some 500 games are half price until July 5. That's to say nothing of the daily deals, which go even further with the discounts; today's offers are a Dungeons and Dragons bundle for $21.10 and an Alan Wake bundle for $4.48. Need to resist the urge to buy a bunch of games I remember fondly but realistically won't play much.
