Colbert Bump: Terraria was an obscure indie game until the Minecraft devs mentioned it on their blog. Sales shot up to the point that it was higher on Steam's bestseller list than Portal 2 for several days.
As in Minecraft, you can let your imagination run wild and build all manner of wonderful things, like imposing castles and sprawling villages, and equip them with a wide variety of furnishings and decorations with elaborate mechanisms hidden within. Also as in Minecraft, most players will promptly discard their imaginations upon starting a new world and build plain wooden box houses with the bare minimum amount of plain wooden furniture, with all rooms identical and arranged in an obvious grid pattern, and one room crammed tightly with crafting stations and chests.
And despite being the main draw of the game, and what almost everything is balanced around, the combat still suffers from this. Players will reliably base their arsenal around the Life Drain introduced in 1.2, either as melee with Vampire Knives or magic with Spectre Armor. Other equipment is largely ignored except for situational use, and ranged and summon builds are all but non-present (and when they do show up, expect the Vampire Knives to be sitting on the hotbar anyway).
In the fallout of the cancellation announcement, Redigit has outright admitted that he never saw Terraria as anything more than "a testing ground" and that his heart was never truly into it. When the fans naturally got pissed by this, he retaliated by refusing to let the new content of the console port be added to the original platform in any way, shape or form.
Elements of the community are angry that there is still not any official mod support but have found various ways to make mods for the game anyway.
Dueling Games: Subverted. A lot of people look on this game as "Minecraft In 2-D", but the only actual similarities are the block built worlds and the randomly generated open worlds. After that the game is basically a love letter to the 2-D era of gaming, using simple but bright and fantastic aesthetics, silly and over the top weaponry, and mythical enemies that drop magical items, where Minecraft has a focus on building and working.
Fandom Nod: In Steam's card collection, the Wyvern card has this note: "The reason your floating city is a ghost town". This is a nod to the fact that many players have wanted to build a city near space, but due to the Wyvern's habit of killing almost everything up there and being near impossible to prevent spawning, it would end up killing everything up there.
Jossed: Some fans believe the guide to be the Wall of Flesh. If the Steam trading cards are to be believed, then it's a different entity all together.
Each new patch seems to do this to at least one item. So far, the Aqua Scepter, Molten Armor, Phoenix Blaster, Muramasa, Rocket Boots, Spectral Armor, Rod of Discord, and Star Cannon have all been brought down to size. A few of these proved so unpopular they were subsequently reversed or replaced — the Star Cannon had its high fire rate restored, while the new Demon and Angel Wings, when worn along with the Rocket Boots, allow for much higher vertical flight combined with negation of fall damage.
One that is actually a blessing in disguise is the Hamdrax being reduced to the Drax, removing its hammer capabilities. This makes it much more useful for removing indoor bricks without also removing the back wall.
Interestingly, 22.214.171.124 nerfs the spread of Crimson, Corruption, and Hallow in Hardmode.
