If Silicon Knights ever finished Too Human (lols), I'd love them to remake this and do the whole trilogy they had planned. A lot of content was dropped from the original, so having the extra stuff put back in would be awesome (there was initially going to be a Templar Knight character, and possibly a chapter centered around Mantarok's avatar, plus there was potentially a fifth magick allignment (yellow)). As for which system, I'm not entirely sure there's a choice if nintendo owns the IP as has been said, but a wii version could even look a heck of a lot better, since this was just a beefed up N64 game.
ED was my 2nd favourite cube game, after RE4. Finished it 6 times, and damn the story is fantastic. Maximillion's descent into madness at the end of his chapter blew me away, it's still some of the best english voice acting I've ever heard. Infact, IMO there was one one weak voice actor in the game, that for Ellia.
Edit: oh yeah, bathtub. Even after the 6th time, I was still all D: when I saw it. It's brilliantly done.
Double Edit: the voice actor who played Maximillion (William Hootkins) died in 2005 from pancreatic cancer. RIP.
