Underwater Exploration Games
I'm in the mood for a game that is based around underwater exploration. The three that come to mind are Ecco the Dolphin: Defender of the Future on DC and PS2, Everblue 2 on PS2, and the two Endless Ocean games on the Wii. Can anyone recommend one (or more) of these over the others? Is there another game that I am leaving out? For my purposes, the visuals need to be believable for immersion, so please keep it DC and newer in terms of platforms. Thanks for the help.
edit: Since it is bugging me, someone please remind me of the name of the PS1 Namco game that would also fit this description.
