I will say that, while the other comment comparing it to Minecraft isn’t wrong to do so, you shouldn’t go in expecting some 1:1, 2D Minecraft experience. Because while they have plenty of similar features, the core of each game is quite different. Minecraft for example is primarily a sandbox game, with lite survival elements sprinkled in. You’re mostly just there to build and farm and do whatever the hell you want, and the game doesn’t differ greatly between peaceful and hard. Terraria on the other hand is primarily an action game with some survival elements. Sure, you can build huge, beautiful cathedrals if you’d like, but unlike Minecraft that’s not really where the game shines at all. Terraria instead shines in it’s exploration (especially when you’re new to the game) and combat.
