Video games are meant to be challenging. They have a learning curve for everyone. However, that doesn’t mean you have to be a pro-gamer. You can be a casual gamer and still have a good time.
If you’re constantly failing missions or quests, you may be suck at the game. You might be ignoring the game’s direction or failing to listen to the NPC. It could also be that you’re playing when you’re stressed, angry, hungry or otherwise distracted. Try playing the game when you’re in a more calm state.
In order to improve, you need to practice the game regularly. You should practice with purpose and record your gameplay to analyze your flaws. You also need to make sure that your gaming hardware is up to date and that you’re sitting properly while playing. Finally, you need to be on a well-balanced diet to ensure that you’re getting enough nutrients to fuel your body properly. Without these things, you’re unlikely to improve.
