Terraria - "It's just a 2D ripoff!"

If you think of the word "Terraria", what do you think? Lots of people would say, "It's just a 2D ripoff!", but honestly, it's not at all. Sure, they both are made out of blocks. SO ARE LOTS OF OTHER GAMES!
I've been playing Terraria for quite a while now, and I'm going to compare some things.
ITEMS:
Minecraft has about a hundred items. Now, let's look at Terraria. Remember a while ago- the post from Redigit- "1000th Item has just been added!"

BOSSES:
Minecraft added it's first boss in 1.0- the ender dragon. Then the wither, just recently in 1.5. Now, Terraria. 13 different bosses. Eye of Cthulu, King Slime, Brain of Cthulu, Skeletron, Eater of Worlds, Queen Bee, Wall of Flesh, The Destroyer, Ocram, Golem, Plantera, The Twins and last, but not least, Skeletron Prime.

NPCS:
Minecraft has 5 or so different types of villagers. Bland. Boring. HMMMMMMMM. And they're not even very useful.
And then there's Terraria- 20 different villagers. All have certain requirements before they can come- so it offers a fun challenge- and a rewarding one too. You can buy practically ender chests- even potions.

ENVIRONMENTS:
Minecraft 1.7 has added LOTS and LOTS of new biomes. But lets be honest- the biomes are pretty bland, with very little differences from another. In Terraria, every single biome has a different purpose- a good purpose too.

ENEMIES:
Minecraft has around 20 enemies. Then Terraria- there's more than I can even count- and the wiki hasn't updated them all, because nobody has discovered just how much there are!

So in the end-
Is it REALLY just a 2D ripoff?

Thank you for reading this rant.
