Territory Idle - literally buy land hire workers sell the land for profit.
NGU Idle - Literally just to fight the power to make money.
Grim Clicker - Monke wack thing that get in way.
Bitburner - MAKE MONEY.
Idle Space Raider - You are basically the space police…
Idle Wizard - Imma just ponder that orb real quick.
Underworld idle - Built on the back of the sacrifice of our comrades.
Your Chronicle - Having a loving father simulator.
Idling to Rule the Gods - Auth-centre’s wet dream.
NGU Idle has too much going on if you ever drop it to feel like getting back into to be honest however this, idle wizard, Underworld Idle and Idling to Rule the Gods are probably the best true idlers of the bunch. Though I haven’t got very far into the orb pondering game and it may become more interactive like NGU Idle does (Which is annoying)
Your Chronicle is very different to your typical idler would recommend not starting with it.
Idle space Raider and Grim Clicker don’t want to be idlers and actively fight you trying to play that way in my opinion.
Idle Territory is not an idler the first 10+ hours have to be played manually it’s a terrible experience.
Underworld Idle you kinda have to just leave running over night sometimes cause the game doesn’t do any calculations when you turn it off but it’s definitely my second most liked.
Bitburner very good would recommend has a nice wiki to get you past the early game content as well.
