D&D, Oldschool or Epic?

All right, so the first question is: what is D&D? D&D is a roll playing game where people create a character and fight againsed monsters and such, collecting loot along the way. That's the textbook definition, but it is so much more than that. There is a whole culture behind D&D, It is hobby, but it becomes more than that.
The game has become a bit of a tradition in my family, my mother played, I played with my brother when we were kids, and now I have a group and we play almost every weekend. Its a social thing, a chance to see my friends who have the same interests as me, to share experiences from different games, and laugh at what this or that character did that time. In some ways, my D&D group knows me better than any of my other friends, because they get to see all the people I would like to be, but can't in real life. It really is a world where your imagination is the only limit.
So then comes the questions. Is it a Cult? Is it outdated? Why play D&D when you can just turn on a computer? For me its really very simple. Yes, its an old game, but its had all that time to get better. No, its not a cult, its no different than a poker group (except considerably nerdier). And why not just turn on the computer? Because then it would no longer be social. Its not all about the game, sometimes its about the people you play with. Its an exercise for your imagination and your brain, it allows you to do what you want, not what the computer thinks you should be able to. The rules are guidelines, and can be overruled by the Dungeon Master. When you are the DM, you are god, you can do anything.
