In a game like RDR2? .....I'll be completing the story and likely all of the side missions, etc.
With a good title, I don't mind savoring all that the campaign has to offer. Depending on how it's developed, sometimes I will opt to complete side tasks first before tackling some main story missions to gain experience, collect weapons/items that might be offered, earn money, etc. ......basically preparing/outfitting my character with better equipment, etc. before tackling more difficult parts of the game. I can also get more familiar with the game mechanics, the world, etc.
