Holy crap you just made me feel old.
I was about your age when the Dreamcast was released. Anyway, Welcome! Always glad to have more Dreamcast fans around. Hope you find the site as welcoming as I have. Everyone here is a pleasure to talk to and one of the best Dreamcast communities around. Don't hesitate to ask questions or contribute. Dreamcasts are fairly cheap and it has one of the strongest game libraries of any system to date. You can probably pick up a console for the same price as a new game on the current gen systems. So just do it, you won't regret it.
Look forward to seeing you around here!
