GOG.com has kicked off their big winter sale, so we've once again entered a prime window for discounted Wing Commander. At 75% off, the entire DOS and Windows lineup can be yours for under $12. We've mentioned this deal every time it's come up, and it's just such a steal that we'll continue to do so in the future. Don't forget that these include plenty of bonuses like expansion packs, official guides and more. There are lots of other deals on the service as well: Star Wars games are similarly about 75% off, including WC contemporaries like X-Wing.
