TheEnigmaticT: Yes. To make it official: We were only running these for February as a test to see how they did.
Hopefully they did well because GoG really could use more sales with both: 1) different variety/frequency, and 2) bigger discounts. These sales covered both of those angles.
I'll be perfectly honest. Despite the low price points I rarely budge on a game unless I see it at 50% (what used to be the lowest discount) -- the reality is I have well over a dozen games on my 'to play' list including two or three on GoG so unless something is offered at a discount there's no reason for me to buy it if I won't be getting around to playing it prior to another big annual sale a la Christmas.
