It seems like you're just overall angry about gaming nowadays? You've mentioned how content isn't hard enough, too vanilla, games nowadays don't keep you engaged. The topic title you chose seems a bit out of place now that you've shared your thoughts...why didn't you just comment on another thread about how you want harder content?
This started when you said XIV had no community, and many of us here shared our own stories and experiences on how this game has made us happy with the friendships we've found. OP has ignored the many people who discussed the various ways you can create a community within the game, and is now just complaining about how games aren't what they used to be. The point of this thread was that there was no community, but there clearly is one, just not the specific, very narrow community OP wants.
Also, why is it bad that teenagers and adults in their mid-20's play MMOs? OP, you were probably a young teenager when you first started MMOs, and obviously you've loved them for a long time. You were once in their shoes...would you have wanted people to give you a hard time and say that you were ruining their gaming because you were new to the scene? Everyone has to start out somewhere, it doesn't make a game or community bad to have a variety of people playing. If anything it makes it that much more beautiful being able to interact with many different people - again, which is possible, because XIV has a great community aspect to it if you use it.
