It's hard to say for 100% certain, but the DC may be my favorite console of all time. I tried to get one at midnight at the local Wal-Mart (the only place in my area that was open at midnight), but I and about 10 other game nerds were disappointed that none of the people working there could figure out how to go to the back and find and bring out a Dreamcast for us. So I got mine from a local shop at 10am.
It launched with SO many games. And coming on the heels of the Saturn (which launched with 2 games, I believe? Maybe 5?), the N64 (three or four?) and the Playstation (4 launch titles), it seemed like it was going to rule everything forever.

Especially given that most of the 18 or so launch games were _really good_, in stark contrast to the Playstation 2's launch games (ugh!). Soul Calibur, Power Stone, House of the Dead 2, Virtua Fighter 3, so many goodies.
I have always really hated the VMU's, though. Terrible idea. And the main menu was so ugly and Pastel-y, really very Hello Kitty when it comes down to it; I wished that they'd have kept the main menu like that on the Saturn, as well as giving some built-in memory. But they were trying to copy the bits of the Playstation that I liked the least; can't blame them for trying I guess.
I've got a "Guide to Dreamcast Games" book made by either Brady or Prima that is kind of amusing and sad, in that it specifies Baldur's Gate: Dark Alliance as a "coming soon" title. That game would've kicked so much patoot on DC... still does on Xbox, but would've been a great feather in the DC's cap.
I think it really failed due to a few things. One would be awful marketing; their weird ads were nowhere near as good as even the weird "Sega!" Genesis ads, or the strange Saturn ads. They didn't play up the sports enough when it could've taken that market handily with the 2k series. Two would be their focus on the arcade games (which I love to pieces) at the expense of the sports games (never got EA on board either) and the opposite end of the spectrum, the RPG games. Sure, PSO and Skies of Arcadia are great, but people need more than that, and those were both late in the cycle. But that's just me taking guesses; who's to say if anything would have allowed them to stay afloat amidst the crazy marketing and hype juggernaut that was the PS2 ("It's so powerful it'll move eighty million more polygons than Dreamcast! It's so powerful it could be used by terrorists to manipulate nuclear missile launches!"). But it would've been nice if they'd have put up a smarter, better fight and stayed with the DC for longer.
Oh, and also.......
Why they never released DC versions of Golden Axe 4, Panzer Dragoon Saga 2, Shining Force 4, Streets of Rage 3, Nights 2....seems like easy money and great potential to me. I know they were all about letting their developers choose what they wanted to do, and that's all fine and good, but hire a GOOD team with supervision of the good grandmasters like Yuji Naka and get some of these games made. I love weird games like Jet Grind Radio, Typing of the Dead and Space Channel 5, but to sell the system to people who remember their Genesis fondly, give them titles they recognize.
