Amazing and unique game!
Graphics - Graphics are smooth, crisp, and colorful. Nothing really stands out and makes you say "wow", but overall the graphics are pretty good. Weather changes, river flows, leaves, fruits, and the morning/day/night change do make the graphics pop a little.
Sound - The sound is good. The music you hear inside buildings and walking around is nice, but nothing impressive. The characters mumble noises are a bit annoying, but you can always make them silent.
Replay Value - The replay value is good, because the game never really ends. You can keep playing and playing and playing, but there will always be something to do. Whether it be catching more fish and bugs, finding more fossils, celebrating more holidays, or making more money; you will always be able to find something to do. Some may say that things get repetitive after awhile, but I still enjoy doing the same things over and over again.
