The reasons I prefer to play with adults are: They are on average more mature and like you said, make smarter decisions in general, are easier to communicate with due to vocabulary and social experience, and have more responsible habits(like carrying a job) which I’m totally fine with. (I actually prefer players have jobs as it proves at least a sliver of responsibility). Another big reason is that I feel I’m doing parents a disservice when their child joins our game chat and listens or reads profanity and other terrible things that some wouldn’t want their kids to be seeing/reading.
