An idle RPG where heroes fight in your name while you only watch
The Idlest of all quests is an open world RPG with multiple heroes that do quests, explore, fight, die all by themselves, and have no idea that you - the benevolent GOD are watching them from above.
Level up your heroes, Summon new ones, unlock new abilities and behaviour's, watch them loose and watch them win. You can't tell them what to do exactly, but you may just as well be able to NUDGE them in the right direction with a little sign from above. Save their lives at the last moment, or let them deal on their own.
