This is one the most under appreciated games ever. Period.
Graphics: This game does have some poor graphics but the more I see it, the more I understand why they didn't change it. It just seems to fit what they had imagined when they first began development so many years ago. It definitely has an artistic feel. Very good in my opinion.
Sound: It screams pirates and adventure! The music and voice talent in Galleon are the highest marks and kinda keeps the games spirit. I really loved it and hey, its just fun.
Gameplay: Galleon seems to have a big "grab" at a lot of gameplay types. Platformer, puzzle, adventure, fighting, etc. I found Galleon's fighting system kinda odd but gets the job done. The platforming is the more what I liked and some of the puzzles were at a good difficulty.
Conclusion: If you love adventure games, puzzles, and pirates, this game is what your looking for even if it may not seem so. Galleon is very under appreciated and should at least be given a shot.
