The Remastered version uses Epic Online Services (or Steamworks) for drop-in/drop-out co-op. Cracked repacks generally do not support this, or they rely on questionable third-party LAN emulators (like Online-Fix). If your sole goal is to cause chaos with a friend in real-time, buy the official version. If you want a single-player sandbox of destruction, the repack is perfect.
: While these repacks often support LAN or "quacked" online play, they do not typically support official competitive matchmaking [10, 19]. Retail Availability Saints Row The Third Remastered-Repack
