The @Steam Lunar New Year Sale 2021 will run from 11th February to 15th. Leaked from an email to Steam partners, and you know, the Chinese New Year is on 12th
No word on any big sales or anything but that is when you can expect to see their next big sale event for the year. Thought I would share about this in case anyone has their eye on a game or two hoping for a deal.
