Just watched the video!
Great as always!
In my opinion, the Dreamcast has probably the best library ever if you consider the number of good games versus the number of released games releasedat all. There are just SO FEW bad games on this machine... So, it is VERY difficult to list only 10...
I will try naming here only the ones that I currently own.
1 - Shenmue II
2 - Garou: Mark of the Wolves
3 - Sonic Adventure
4 - Crazy Taxi 2
5 - Capcom vs. SNK 2: Millionaire Fighting 2001
6 - Soul Calibur
7 - Street Fighter III: Third Strike
8 - Eternal Arcadia (Skies of Arcadia)
9 - Power Smash (Virtua Tennis) 2
10 - Jet Set Radio
