Terraria is a 2D game released in 2011. A lot of people who haven't even played the game call it a ripoff of minecraft, but as someone who actually experienced the game, I can officially say that it's much more than that.
For starters, Terraria has a lot of depth. There are many different ways to play the game, and lots of content in general. Hundreds of creative weapons, cute pets,. And awesome accessories keep you hooked as you try to collect them all.
You can make yourself as overpowered as you want in the endgame, but you start with almost nothing. It's fun to make progress in the game, slowly making yourself more powerful.
This game also has many, MANY pop culture references. You can fight a ninja slime with a bow that shoots flaming bats while wearing a creeper costume and riding a goat from hell!
If that doesn't sound fun, I don't know what is.
And finally, the game has a MASSIVE and very active community. Every day new videos, fanart, and mods are pumped out at alarming speeds.
Ah yes, the mods. There's tons of them!
The game already has lots of content, but the mods sometimes make terraria into an even better game than it was before. New bosses, mechanics, OP weapons, what's not to love?
