Excellent thread, about time the Saturn was mentioned. Saturn really excels with 2D. Hence the superior versions of SHMUPs and 2D fighters. Sega put in a pretty good showing too. Literally over 1000 games never made it out of Japan unfortunately.
My top 10:
1. Panzer Dragoon Saga
2. Radiant Silvergun*
3. Sega Rally
4. Psychic Killer Taroumaru*
5. Castlevania: SotN
6. Dragon Force
7. Panzer Dragoon Zwei
8. Dodonpachi*
9. X-Men Vs Streetfighter
10. Thunderforce V*
*I Only had pirated copies unfortunately
/v/ did a pretty good Saturn summary:
