I love the Ecco with lazers picture. I kept saying "pew pew pew" tonight, and now it's an inside joke amongst my friends... and it's my background pic on my computer...
I own and played Ecco the Dolphin: Defender of the Future on the Dreamcast (and still got it). Stopped playing back in mid 2001 and still got the save.
The moment Ecco the Dolphin turns into a SPACESHIP to stop the FOE from screwing up the balence between dolphin and man is the moment the deep sea adventure turn into deep shit.
Believe me, that adventure is an absolute bitch!!!
After you undo both man's (A really screw up future) and dolphin's (a bright but still screwed up future) futures you will have to go to the FOE's hideout and face even MORE screwed up crap. And don't get me started on the lies that the crystal will give you.
