Short Answer...Cause it's F'n awesome.
Cause it's F'n awesome!!
So growing up...I was 5 when the Genesis came out, and I just fell in love with it, and Sega. Sega fanboy all the way, had the Sega CD attachment. Then had a 3DO, and a Playstation, didn't discover the Saturn till it was pretty much finished, but loved it, and it reignited my love for Sega. Then the Dreamcast hit, and I was just floored. I still remember trying a demo unit and playing Sonic Adventure, and my jaw just hitting the floor when crossing the bridge being chased by that damn whale.
To this day....as good as games look, nothing has even floored me like that did.
The Dreamcast then just gave me so much joy, happiness, and new experiences. Now that I'm 36, getting older, I miss that feeling, and nothing really gives me that feeling. Discovering this site, and getting my Dreamcast back online...gaming with fellow Dreamcast gamers, have given me that warm n fuzzy feeling again, and it's just freaking awesome.
But even before that, I'd break out my Dreamcast from time to time, play thru Skies of Arcadia again, Grandia 2, Sonic Adventure, Sword of the Berserk, MDK 2, and so many other great gems. I own over 140 DC Games and it's just such a special console to me. I'll play the damn thing till I die
