Objectives are something everything video game needs. Without them, there would be no reason to play. In video games, it is common to have a main objective, and then side objectives. These will sometimes grant the player some advice, or something useful that might help them later. There are also many different types of objectives, which can lead to a lot of different game or play styles.
A common objective in video games would be to kill a specific enemy. These are most common in fight person shooters, where you might have to clear and whole room to move on or complete a level. A good example of a game with an objective like this would be a game like Minecraft, in which you need to kill a dragon to complete the game.
Another fun one would be to win a race. Games like these are created for the fun of competing against friends and winning races. An example of a game like this would be Mario Kart, where you race around different courses to win a grand prix.
A common objective for side quests would be exploration, or finding a specific point in an open or closed world. A lot of RPGs have side quests where this is the goal.
An uncommon or hidden objective would be changing a character's alignment. Although uncommon, it is the hidden objective of Undertale, where in the True Pacifist route, you must convince all the monsters to not fight anymore. In other words, you have to change their alignment.
Chase is another objective. The only example I could think of is a side objective that would greatly help the player in Star Fox, when you have to chase around the enemy in a dogfight to destroy them.
Professor Layton also has an objective, which is to solve the puzzles to solve the mysteries. This could be counted as finding a solution.
There are a lot of games have a rescue or escape objective. A game with this objective would be Rainbow Six Siege, where two teams have to eliminate each other. One of the modes of play if to have to rescue a hostage being held by the other team by scouting out the place they're hiding and then attacking in a strategic way.
Another one is to commit a forbidden act, which is essentially an act the player can commit, but is maybe compelled not to. An example of a game with this feature would be Yandere Simulator. Although the game is still in development, it is hinted that killing a person is possible, yet maybe not wise. It is possible, but it wouldn't have a drastic affect on the characters in game when it is completed.
Construction is another objective, manly in games like the Sims, where you build your Sims a house to live in, and build up relationships and live in a virtual world.
The final objective type is outwit, meaning the objective would be to outwit someone or something. An example of a game like this would be a card game like Exploding Kitten. The aim of the game is to be the last one standing, and collect Defuse Cards that can save you. A way to do this is to draw, take it from another player, or trick another player into giving it to you.
Overall, these objectives are all linked in one way or another. A game with exploration would most likely have a greater goal, or a chase objective might be a side quest or minigame, meaning that picking one when creating a game would be both unwise and boring.
We also took a brain gender test, and mine came back as male. At first I was confused at the result, but I realised that it was true that I sometimes don't plan things as much as I should. On the other hand, I sometimes or plan projects and panic when they don't turn out how I planned. Of course, I had another reason why I was so good at the male questions. Because of how many puzzle games I play, I am good at recognising patterns or similarities between two shapes.
I will admit I guessed a few, and had I not been timed or as panicked as I was about realising I was being timed, I probably would've gotten a different result.
