Terraria

Terraria, often initially perceived as a "2D Minecraft," has evolved into a sprawling 2D sandbox action-adventure with a staggering amount of content. Developed by Andrew "Redigit" Spinks and a small team, it boasts over 5,000 items, 400 enemies, and more than 30 bosses. The game's longevity is remarkable, with continuous free updates for 13 years, a dedication that puts many AAA live-service games to shame. This commitment has contributed to over 70 million copies sold across all platforms by May 2026, making it one of the best-selling video games ever.
