A full-fledged official return of the classics Tomb Raider Legend and Legacy of Kain Soul Reaver is difficult to expect, so fans are getting down to business
Tomb Raider Legend and Legacy of Kain Soul Reaver have a definite fan community. They never got a remake or some kind of re-release.
Not everyone is ready to come to terms with this state of affairs and are trying to make projects based on or their own remakes. Projects like this come with a risk because they may file DMCA (Copyright Infringement).
