Your first week making gaming content should end with one finished piece you can learn from. It does not need a channel trailer, daily uploads or a promise of income.
Choose a subject you can explain clearly: a decision in your own match, a beginner mistake, or what happened when your group tried a different approach. Use footage you have permission to publish and agree before including other people's voices.
A suggested week
First session: choose the point. Write the viewer's question and your answer in one sentence each. If you cannot finish the answer, the idea may be too broad.
Second session: record a sample. On a desktop setup, the OBS quick-start guide recommends testing settings before a real recording or stream. Record only enough to check that the game and your explanation are understandable.
Third session: build a rough edit. Remove the waiting, repetition and material that does not help the point. Keep a copy of the source files.
Final session: watch with someone. Ask what they understood, where they lost interest and what was unclear. These are observations from one viewer, not audience analytics.
The sessions can fit the days you have. This is a project outline, not a requirement to post every day.
Measure completion first
Keep a short note with the idea, actual time spent, problem encountered and one change for the next video. View counts can come later; they do not tell you whether you captured clean audio or explained the decision well.
If the week becomes crowded, reduce the edit or move publication. Planning around exams applies to creative commitments too.
Publish when the piece is ready and the people involved understand where it will appear. Then choose the next question, using what you learned from making this one.
