It DOESN'T compare...I have both versions myself and the Sega CD version of LoT is so subpar versus even the US release, it's not even funny. It's a shame such a beautiful game would be reduced to such a flickery, slowdown-prone overdithered washed-out-looking game that was missing a few things, was too easy, and overall felt "cheapened" by the weird, amateur effects they used in parts of it. If you'd never played the original, then sure, the Sega CD version would probably be quite the kickass game, but compare it to the original and it falls on its face.
