talking to other villagers in ac:ww when i was around 4 years old helped me with learning to read. i had a basic comprehension of the alphabet and all at that age, but playing ac was definitely good reading practice. i still remember always misreading the text bubble as it loaded my save file though lol
Animal Crossing actually helped me to read. I was very, very young when the first game came out and the dialogue was difficult for me to understand, but it was my biggest motivation to learn so that I could play the game properly.
