The verdict
The faction-swapping grandaddy of strategic idlers: align with elves, demons, fairies and more, each rewriting how you play. Three stacked prestige layers and a decade of depth keep it a genre benchmark.
Hot take
The spell-timing and faction combos turn 'idle' into a puzzle you actively solve. It's proof the genre had real strategic ambition years before the current wave — and it still holds up.
