I always try to debate with myself whether I liked the SNES or Dreamcast more, but I think in the end, I lean more towards the latter. I don't even know if I can explain it. At the time of its release, it just excited me a LOT, and in particular is was Sonic Adventure that first got me drooling over the console. After that though, the good games just kept coming. Rush 2049 is another particular favorite of mine. I still own like 50 DC games, and I forget most of them since I haven't had the console hooked up in a while.
I never heard of Sharks, but I used to live on the west side so I wouldn't have been close to it. To be honest, we've never had many good arcades, but that one sounds pretty good. Wish I saw it.
I agree on the Saturn though, it was a great console. Sadly, I only own a Japanese version, so I have limited games (only own like 10). Nights never gets old. I gotta get a US console sometime that way I can increase the number of games I can play with it. And you know, games I can understand.
Where on earth do you see Dreamcasts on eBay for $500? I had a quick look and see lots for well under $100, games included. I almost feel like picking up a second one in case my primary ever decides to die.
