Like many things in life. You had to of been there or experienced it to truely understand. (Halo 1 LAN parties anyone?)
IMO, the console was completely ahead of its time. It did have online play before the other consoles, memory cards that were absolutely unlike anything that had ever come before it. You could use these memory cards like little tamagochis or something, play games on them, and they displayed information while you were playing a game. Like in Resident Evil it showed the heart beat sensor :)
Sonic Adventure was my fav sonic game, and still is imo... I remember playing it to death for days straight when it came out and actually threw up twice due to motion sickness, and still I loved it.
And of course, Power Stone 1 and 2 both hold a special place in my heart.
