Just want to mention that this list isn't really good for showing that the DC had great games in comparison to other consoles. (I don't doubt it has got a lot of great games, but I just want to point this out.
) The reason is that Flag to Flag/Super Speed Racing is the only game in that list that is exclusive to the Dreamcast.
Rez, Space Channel 5, and Crazy Taxi were all released on the PS2 as well.
Space Channel 5 Part 2 was also released outside of Japan for the PS2, but not for the DC.
Although it didn't have the first, Virtua Tennis 2 was also on the PS2. The same goes for Soul Calibur, as the PS2 got Soul Calibur II and III.
Worms Armageddon was released on the PS1, and so it could also be played on the PS2.
And the remaining titles I haven't commented on were all released on other systems(N64, Gamecube, Xbox, etc.).
