The changes from The Silver Star --> Silver Star Story are much more significant than Eternal Blue --> Eternal Blue Complete.Possible spoilers:Silver Star Story changes (that I can think of off the top of my head)- No random battles on world map- Different music- Quark first makes Alex undergo a small trial before giving over the "diamond" (Sega CD no trial that I recall)- Weird Woods covered in fog preventing passage to Saith. (In Sega CD a bridge was out and you had to find an ax for the Carpenter to rebuild it.)- Meet Nash in front of the house of the old woman (Sega CD you meet him in Saith in the boathouse)- Boss added to the ship (Sega CD had no boss here)- Meet Royce and Phacia (Sega CD they don't exist)- Dross steals diamond and you first seek Mel's help (in original you just go after him yourself without asking for help if I recall correctly). There is no duel with Mel- Luna meets Ghaleon in Vane (Sega CD she didn't join you)- Silver Mirror no longer needed to enter the Tower with Mia (but metal equipment is now useless)- Ghaleon captures Quark- Ghaleon and crew still capturing girls despite being told by Quark that Luna was the one (wtf plot hole)- No turtle ride to Damon's Tower (and no special song requirement either)- Singing to unlock Blue Dragon Cave (Sega CD does not happen)- Alex and co. Fight Black Dragon, do not kill him (Sega CD they kill him and Ghaleon taunts them)- Sword of Althena is in Burg at Dyne's Monument- Nall "figures out" he's a white dragon at Dyne's Monument (Sega CD he's told in- Ghaleon only has one form (Sega CD has two forms)- Small playable epilogue present (Sega CD does not)
