Good news from GOG this morning: their 2013 #noDRM Summer Sale has begun in earnest, with many games available for half their normal price, and with daily sales that see games discounted to as much as 90% off.

These daily deals are kind of a gamble, a fun little game that GOG plays. Right now, for example, you can grab games like Ultima 7 (both parts!), Thief Gold, Arx Fatalis, and even System Shock 2 (among around 500 other titles, I believe) for 50% off. You can also get most of GOG’s Dungeons & Dragons games for 9080% off today only. Tomorrow…well, who knows? Maybe the Ultima games will come up as the daily deal, or the Wing Commander games…or some bundle involving System Shock 2, for that matter.

And that’s the game: do you take advantage of the 50% price cut, or wait it out to see if the game(s) you really want go on sale for an even better discount?

Oh, and for the next 40-odd hours, you can also nab a copy of Torchlight for free. Pick the game up; it’s addictive and fun.

The sale goes on until July 5th, so be sure to keep checking back every day to see what new daily specials GOG throws our way.
