Let’s be honest: Mafia is classified as "abandonware" by many preservationists (though Take-Two/2K still owns the rights). If you own the original game, downloading a repack for preservation and compatibility is generally considered acceptable. If you don't own it, support the franchise by buying Mafia: Definitive Edition (the remake), but keep in mind the remake changed the gameplay significantly. For the true 2002 vibe, the repack is the only way.
