Memorization has been part of video games since the beginning. Like it or not - but being good at memorization is a video game skill. There are countless amount of people who love the Dark Soul's series and those boss fights are all about memorization. In fact, many people love FFXIV because it's one of the only MMOs that offers that old NES style memorization gameplay. Most MMOs you can be good at purely by playing a lot and earning the best gear. FFXIV actually requires you to have gaming skill. I for one enjoy it.
