Research 

I have recently been listening to 16-32 bit game soundtracks to get a good feel for how a good chiptune soundtrack sounds. I have been listening to games like the legend of Zelda, a link to the past, Undtertale and final fantasy. Through this, I have figured out that to build suspense in a game and to set a certain mood it depends very much on the pace and pitch of a song. a slow and slightly high pitched song is happier and calm than a really fast song.

I have also been replaying a number of games to see how they lead a player through their game. For example, Witcher 3 gives the player an objective that they must complete a story quest to proceed further into the game or do side quest to increase their level or earn money.
