Don't most companies today use Securom 7?
Starforce has (had?) been gaining popularity amongst publishers, as it is considered to be one of the hardest copy protection schemes to crack. While it's true that a majority of games still use SafeDisc or Securerom, Ubisoft's decision to drop Starfoce based on consumer feedback should make other publishers think twice about using Starforce themselves. Also, quite a few high-profile and/or higly rated games have been using Starforce, as evident by this list
. Brothers in Arms: Earned in Blood, King Kong, Prince of Persia: The Two Thrones and Splinter Cell: Chaos Theory are just a few examples.
It was Codemasters that used that copy protection scheme, and included it in Operation Flashpoint IIRC. I seem to recall that it wasn't a big success, and was dropped some time later. I think it was because the games that would use FADE got a reputation for being buggy as hell, when in reality it was just the copy protection software kicking in, and also because the protection was kind of buggy and would sometimes affect paying customers as well.
