World of Water: Great Journey is a unique strategy-exploration game that takes place entirely beneath the waves. You manage a colony of sea creatures, balancing resource gathering with defense against predators. The 'Great Journey' refers to the migration aspect, where you must lead your school of fish and other aquatic allies through different oceanic zones, each with its own ecosystem.
The visuals are the standout feature here—the bioluminescent deep-sea levels are stunning. The gameplay feels like a mix of an RTS and a survival game. You have to think about the food chain; smaller fish gather resources but are vulnerable, while larger predators in your group act as guardians. It’s a refreshing setting for a strategy game and offers a sense of wonder that many land-based games lack.
