I would like a couple of things. I believe these would improve minecrafts game play.
1-Swamp mobs, like alligators or toads
2-Filler NPC's(Background Mobs) Like birds or frogs or crickets. With sounds being important. It would make minecraft feel less empty, more alive.
3-More biomes, like a volcanic biome. With the inevitable explosion. A savanna biome, with bigger cats, and more mobs like an elephant, or a coyote
4-Thirst. This would create a new element and challenge(Disabled on peaceful). This would also create a more, desert feeling, to deserts. This would create a new obstacle for players crossing deserts. It would be more realistic.
5-Giant sandworms. Imagine a giant hellworm, blazing out of the desert sands and tunneling back down below. That would be a challenge. And vultures, stupid in terraria, awesome in minecraft!
