A 2-D game created by companies Re-logic and 505-Games, it involves aspects much like the indie game 'Minecraft' and some beleive it to be a cheap copy of Minecraft.

Terraria is a fun 2D game that will keep you hooked for hours. Terraria is claimed to be a copy of Minecraft, however, the only similarities between the two are building and monster killing. There is a ton of content including bosses, weapons, equipment, classes, NPCs, and more.

On March 16th, 2020, Terraria Journey's End (1.4) was released. Journey's end is the final major content update of Terraria.

The best game invented my humans (I don't know about Martians or that stuff.)

A 2D sidescroller game made by Re-Logic. A fun and pretty addicting game that's concept is similar to Minecraft. Some people say that Terraria is just a copy of Minecraft, but the only thing that's basically the same is the building and the monsters.

Some angry 10 year old Minecraft fanboy is probably reading this and is like " OMG TERRARIA IS JUST A RIPOFF OF MINECRAFT!!!!11" And the truth is that it really isn't. While the graphics isn't the best, there is way more content. 20 main bosses, 3 of which are Old-gen and 3DS exclusives. 14 event bosses, 4000+ items, and much much more.

Terraria has 4 classes you can play with, Melee, Ranged, Mage, and Summoner. You utilize swords as Melee, guns, bows, even different types of arrows and bullets for Ranged, spell tomes, staffs, even prisms for Mage, and minions that can be imps, or can be a giant dragon. Terraria also has different armors for different classes, and accessories that buff you or just make your life easier.

And before you say "Minecraft has mods and Terraria doesn't", It does. Terraria runs mods on something called TModLoader, and as of update 1.4, it has become the free dlc of Terraria. One of the most popular mods, The Calamity Mod, added 25 new bosses, 12 mini bosses, and nearly 2000 new items. If you want a cheaper alternative to Minecraft, Terraria is your best option.
I mean, at least Terraria isn't just you destroying your mouse when the dragon swoops down.

1. Plural for ‘Terrarium’
2. An amazing side scroller game with many bosses and cool stuff. Some people say its 2d minecraft, and thats wrong. In fact, terraria was the only reason i am writing this. Ignore 1. This is what the word was made for. Back to ‘2d minecraft’. It came after minecraft, so some people call it a ripoff. Ok, yes, it IS 2d minecraft, but at least with 1000000000% more content. Try it, you’ll like it. Oh and please add this to urban dictionary, i am in school writing this and can’t risk getting into trouble. FOR all that hard work. Oh and one more thing....

Impending doom approaches...

Terraria is a game made by re-logic in 2013 its inspired by minecraft

A 2D Minecraft ripoff in the eyes of most people who never played it before.
It IS a 2D side scroller, so that's right. It also has WAY more progression, variety, and replayability. There are VERY few bits where Minecraft is better than Terraria, which are:
-enchantments (there is a reforge system though)
-complexity
-difficulty (but then again there is journey/classic mode)
-NO CREATIVE MODE
