I think it's safe to say that there's a lot of people who are trying out this game that haven't tried other MMOs before because it's the most accessible MMO on console platforms. And while I don't necessarily agree with the idea that console players can be infantile, you do get a certain segment of people who can be like that.

That being said, as a console gamer myself, the good thing is that not everyone is like that. Unfortunately, hardware parity (the lack of a working keyboard) and education ("Did you know that you can use the PlayStation App on your phone with your PS4 and use your phone's virtual keyboard to type?") prevent these same players from communicating effectively with people who do have keyboards.

I also agree with Vahlnir that we have a very different community here in Final Fantasy XIV and the Final Fantasy MMOs in general. My experience has been that we're more welcoming and open than most other games in the genre.
