What is the best time during the year to release DLC for a medium game on Steam?

Question

Marketing

The average is not the top, but it's not the bottom either (about 2 million sales all the time).

Answer 1

I would do this:
1. I would take conditional competitors in a niche and draw up a table, when and who posted DLC, what are their indicators
2. I would study the "seasonality" for this class of games in search engines
3. I would read additional materials (perhaps there are ready-made studies, or indirectly related to the topic)
Based on paragraphs 1-3, I would make a decision.
And yes, of course - it all depends on the context, you need to look at the activity / loyalty to the purchases of your audience and make the final decision.

Answer 2

Depends on audience and sales history. Impossible to give a definite answer
