There are several ways of finding out if a version of SH3 has Starforce.
However most require the game to be purchased or viewed first!!

I don't think anyone who produced a SF-free version ever made this fact known in their sales publicity.
For this reason I've ended up with three versions of the game. 1) The original, 2) a budget version bought this Easter and 3) the Focus International version mentioned in this thread :

The first two do have Starforce, the last one doesn't.
Edit: Should mention here that someone in the USA reported a problem with the Focus version which he thought may have been caused by this being for the European market . It doesn't have an obvious area installation code but I can't guarantee that it doesn't have some other form of area protection.
Personally I would have been happy to settle for the Direct2Drive download version. Unfortunately as a European resident I couldn't get it!!
