Terraria

Terraria is a 2D action-adventure sandbox game with heavy survival and role-playing systems, developed by the independent studio Re-Logic and first released on Windows in May 2011. The player creates a character, drops into a procedurally generated world with a Guide and a few copper tools, and is left to dig, build, craft and fight through a world that runs from the surface forests down to the Underworld. Progression is driven by bosses and gear rather than levels: breaking a Shadow Orb or Crimson Heart summons a world boss, defeating the Wall of Flesh hardens the entire world into Hardmode, and every major boss unlocks the next tier of ore, armour and weapons. The game is classless in the traditional sense, but gear splits cleanly into Melee, Ranged, Magic and Summon damage, each with its own armour sets, accessories and endgame weapons. It has been supported for over a decade with free major updates, most notably Journey's End (1.4) and Labor of Love (1.4.4), and Re-Logic has sold tens of millions of copies across PC, consoles and mobile.

• Classless Gear Progression — There are no levels or experience points. Power comes from armour sets, weapons, accessories and reforges, and every boss defeated opens the next tier of ore, bars and gear rather than a character level.
• Procedural World Generation and Biomes — Each world is generated with its own size, ore distribution, floating islands, pyramids, Corruption or Crimson, and Dungeon layout, so seeds and world size are the main variables in every run.
• Boss-Driven Progression — The campaign is a chain of summonable bosses, from the Eye of Cthulhu and Eater of Worlds through the Wall of Flesh to Plantera, Golem and the Moon Lord, with summons built from world materials and altars.
• Hardmode Conversion — Defeating the Wall of Flesh converts the world to Hardmode, spreading the Corruption or Crimson and the new Hallow, spawning new enemies and ore, and turning the Dungeon and Underworld into far more dangerous places.
• Four Damage Classes — Melee, Ranged, Magic and Summon gear each have dedicated armour sets, accessories, damage-boosting prefixes and endgame weapons, so a build is defined by the equipment line rather than by a class choice.
• Building, Housing and NPC Happiness — Players place blocks, furniture, chests and light sources, and NPCs move in when valid housing exists; since 1.4 the happiness system rewards grouping NPCs by biome and reduces prices through pylons.
• Events and Invasions — Timed and triggered events such as Blood Moon, Goblin Army, Solar Eclipse, Pirate Invasion, Martian Madness and the Pumpkin and Frost Moons gate unique enemies and drops outside the boss chain.
• Shimmer and the Aether — The 1.4.4 Aether biome under the ocean adds Shimmer, a fluid that transmutes items into other items, decrafts crafted gear back into components and converts NPCs into their shimmered forms.
