Pixelmon changes the game a lot, but it is well worth it. In fact, it's better than Minecraft all together.

Archimedes ships mod, its really fun to fly your custom built ship or sail across oceans with a boat. There's tons of reviews on it on YouTube, just Google it and the download should come up.
