100 years war - Idle is an engaging idle RPG that puts players in charge of raising Eco, a mysterious force that defeats monsters and helps purify the world while letting you progress with minimal interaction. The game combines simple, approachable mechanics with layers of growth: collect resources, complete quests, summon helpers, and explore dungeons like Mimic and Golem to strengthen your Eco. Casual players will appreciate the low-maintenance gameplay and generous launch gifts (50,000 Gems and 200 Draw Tickets) that speed early progression, while social features such as guilds add cooperative depth for longer-term players.
