Or maybe that's just somebody's cynical way of saying they're having a sale. That's probably it.
Actually, that's exactly it. GoG is having a sale. Just in case you're disappointed that you managed to avoid the Steam one, or something. Honestly, though, I expect that more people resolved to buy fewer sale games than more this year, especially on PC, so calling each sale line-up a 'resolution' seems a mite mean.
Still, if you've cash (and time) to spare, you've until the fifteenth to hop on over to GoG and buy yourself some cheap goodies.
