SquareEnix’s Final Fantasy Crystal Chronicles is one of the few Gamecube games to REQUIRE a Gameboy Advance with GC-to-GBA link cable for each player.
Each player uses their GBA to manage their inventory, gil, equipment, letters, and more. This way the party doesn’t need to stop whenever someone wants to make a change.
Personally, I prefer this original Gamecube release over the Remastered version of Switch/PS4.
