But keep in mind, one of the GOG team posted this on the GOG forums:
Not everything will be on sale for the entire period.
Square Enix games will only be on sale for one week. Bohemia Interactive games and Retro City Rampage only for 2 weeks.
We will have announcements 48 hours before the discounts on these titles stop to make sure everyone knows.
