I had the Dreamcast back then, It had so many great games like Soul Caliber, Sonic Adventure, and a whole lot more. I got it for christmas and I couldn't stop playing it, one of the best experience of my life

I really like Sonic Adventure more than Super Mario 64 or Galaxy

Mario go's just too slow for me..

Dreamcast...hmm lets see...

Sonic Adventure 1 and 2...last time sonic was a dominant as a mascot.
Resident Evil Code Veronica...last great resident evil game until 4
Shenmue 1 and 2...nothing to say except wow
Ikaruga...rated 89 on xbox live in 2008
Headhunter...probably one of the most under rated games ever
Skies of Arcadia...Best RPG that gen until Final Fantasy X came out
Soul Calibur...rated 10 by pretty much every magazine and website at the time and rated 98 on metacritic
Seaman...WTF?
Quake 3, unreal tournamet...first real online fps experience for a console
2k sports lineup that slaughtered what EA was offering the same years.

Considering Sega did all these on the dreamcast achievements pretty much alone(with small help from capcom as they supported it until the end) in a time frame of less than 2 years in North America speaks for itself.

Like ssj12 said, even Nintendo first party lineup couldn't touch sega's at that time.

Campcom vs. SNK 2

Marvel vs. Capcom 2

Street Fighter 3

SSF2T

Pure awesomeness, I still have mine.

Guilty Gear X

Fatal Fury: Mark of the wolves

Last blade

Best Street Fighter Alpha 3 ever made for a console :)

I know this is blasphemous, but I actually like the PSX version of SFA3 best.

Yeah, can't forget Garou, it's in the top 5 2-D fighters ever.

 Whaaa...but...how?...whoa...where am I?

i loved the dreamcast poerstone and soul calibur were never off in my house

don't forget Crazy Taxi and Virtua Tennis..

(not that it matters really, but for the many disbelievers, IGN gave them a 9.6 and a 9.4..)

still play on my dreamcast although the battery in my vmu went years ago so i can't play with my chaos' anymore. still love playing powerstone, soul calibur and the legendary marvel vs capcom, the dreamcast was probably the last time i ever enjoyed fighting games other than the smash franchise. i really feel like playing grandia again now although i'll probably give up on that mayor who eats all the villagers, he was mega solid for an earlyish boss.
