So each game, but primarily the first six, started life on one console but eventually got whored out to several different generations of systems. If you were talking to a guy who had never played any FF game and you wanted them to get the best experience possible, which version of each game would you recommend?

Example:
FF1 - NES! It's the original and only pros can beat it. All other versions are too easy.
FFII - Dawn of Souls. Bonus stuff.
FFIV - DS. Better script, addition of voice-acting.
FFV - Advance. It's the only good version.

Note; these are not my opinions. Just stuff I've heard over the years.
