My favorite system of all time.
This one was easy. Sega Saturn is my favorite system because it has so many great 2D games. I like 2D a lot more then 2D and thats why I like the Saturn so much. It also had 4 games in My top 10.
A lot of great fighting games if you are into that genre. 20+ 2D shooters available.Nights into Dreams is my favorite 3D game of the Saturn/PSone/N64 Era.
A lot of great games are import only so you have to do a good amount of research to get the most out of this system. Its dead so no new games will ever come out.
