See, I really don't like Terraria that much.
But what I envy is its amazing updates. If only Minecraft could do the same.
Take a look: in the most recent Terraria update, most existing bugs were fixed and TONS of new stuff was added.
Not to go off topic here, but here's some of the bits from the changelog:
New Enemy - Lava slime
New Enemy - Hellbat
New Enemy - Demon
New Enemy - Jellyfish
New Enemy - Shark
New Enemy - Vulture
New Enemy - Crab
New Enemy - Antlion
Oceans are now slightly larger and generation layout has been improved. (Requires new world.)
Cactus now grow on sand.
Coral now grows in the ocean.
Imagine if Minecraft updates were like that. Some of you may disagree, but I would stuff myself in happiness if oceans, explosive arrows, crabs, antlions and boomerangs were added in ONE update.
