Note: Although I don't own this game on GOG, I do own the original Genesis/Sega CD version. Let me start by saying that the game itself is excellent. It's a bit slow to start and the writing isn't terribly original, but overall it's a very good RPG. Had they done a straight port, I'd definitely be giving this a 5/5. Problem is, they decided to go back and change the graphics. The beautiful Genesis backgrounds were replaced with a bunch of high-res redraws, which look terrible because the NPCs and most props still use their Genesis sprites (which were drawn in a very different artstyle). They also added in those horrible character portraits... I don't even know where to start on those. Normally I wouldn't take off stars just for bad graphics, but the Genesis version of Pier Solar was quite beautiful so it's a real shame to see this.
