Since I began streaming in August 2017, I have played a huge number of many kinds of games. The majority of those I have streamed have been single-player story-heavy games. Many of them, such as open world games, will also be full of side quests, activities, relationship building with NPCs, management sim aspects, or even a huge pile of collectables the player can find for various reasons. Some games obfuscate these objectives and leave them to be simply a bonus to your regular gameplay. An example of this would be the Fallout series, where you can find the bobble-heads or magazines and gain a small boost in stats. Other games will emphasise these side activities by displaying a score menu that tracks your progress or even giving you a showcase of these achievements in the form of unlockable cosmetic content.
