I guess it really depends, if part 1 is very different to "part 1" in the full length then potentially it would be interesting to have it, but as an entry in the db it would most likely only be 1 anyway.
(Same goes for games that have multiple entries with demo(s) and final versions, these will all be 1 entry in the db, and if the demos are to be included at all they will be available as "extras")
