If you thought that was something, you should play Ecco II... it has suspended water very much like the bubbles in "The Veil". Yes, Ecco was one of the things that came to mind while playing this game, along with Metroid (exploration and the jelly costume) and Touhou (some of those bosses' attacks). As I posted in my review of this game (I'm not a professional, its just for a blog nobody looks at... was planning on showing it off to you folks at some point though), this game basically succeeds in what Ecco wanted to achieve... (keep in mind that for its time, Ecco was innovative... it just aged very poorly, though I still love the game)
I would love to see a mod that is a homage to Ecco, but more importantly I'd love to see a mod that explores the story of Ecco 3. I'm not sure if any information as to what would take place there was hinted at the Dark Sea forums, but if they finally told us the third chapter (and not Defender of the Future, though I wish I could play it) this game's robust level editor probably has everything the game would need to do an Ecco 3 justice.
