if you ever wanted to be an Ironwoman in RuneScape (a mode of gameplay where you can't trade or get help from other players in hardly any way), but didn't want to actually have to perform all that grind, i highly recommend Melvor Idle.

it's a really good, well designed game that's extremely similar to RuneScape to the point of being a near carbon copy, except it's single player, has zero graphics, and lets you afk as long as you want. And Jagex liked the idea of it so much that they bought it. makes a ton of sense to me, since RuneScape was basically already an idlegame with extra steps. it's really fun, and probably the most feature-rich true idlegame out there.
