Knowing the main human brain limitations and following a UX framework is a great start, but it’s also critical to apply the scientific method and establish a UX pipeline in order to find and prioritize the biggest UX issues to fix. Solving problems is relatively easy. Finding and solving the right problems is what is difficult. And since humans are biased, relying on the gut feeling of different members of the game team (or even sometimes executives), all having their own subjective perception, scarce attention, and fallible memory, can lead to costly setbacks. This is why is it important to rely on UX research to identify and prioritize issues. UX researchers use the scientific method to pose hypotheses with the game team, design experimental protocols accordingly, and then gather and analyze data while removing as many human biases as possible. Once the most important issues have been identified, the team then needs to figure out why they are happening.
