Lets get the "business side" out of the way:
When you thought of the games you played as a kid what happened? Did you get flooded with happy memories from the past? If so that is what normally happens to most people. You may wonder why that matters. To put it simple that question of 'what was your favorite?' triggers a response! That is a BIG DEAL. again Why? When a person sees something and it causes a reaction they stop "scrolling" and that few second delay is what may make them keep looking or push a button to see more! That is the main goal!
