I agree with a lot of that list, espicially the tennis games. How many parties did I go to with tournaments for those 2 games? While I remember 3rd Strike being on the Dreamcast, seems to me the one to list would be Marvel Vs Capcom 2, it's the one that had the infamous Dreamcast feel. Third Strike really started to capture me when it got to Xbox, so I'd mention it in the "and others". Speaking of other fighters, I don't know if this was among what they were thinking but UFC was a very intense grappling game at those said parties and maybe my favorite under Shenmue. I picked up a lot of this list after dreamcast died at used game stores for a buck a piece.
There will also never be a better Tony Hawk than Tony Hawk two for the Dreamcast.
That said, I wouldn't say the dreamcast was the golden age of gaming because everything was either Gold like this list or, as the majority was, total crap.
