Endless Frontier
A 2018 Korean idle RPG that's still pulling a 4.3-star average from 153,000 Google Play reviews eight years on, built around a twelve-unit auto-battle roster and a genuinely layered guild-and-arena social game — undercut by a permanent roster cap, a bolted-on NFT feature, and a client that hasn't been updated since the studio's attention moved to its own sequel.
