Want your time spent noodling around with idle games to actually bear fruit? Bitburner is an incremental-style idler that casts you as a terminal cowboy on the world wide web, hacking, stealing, and scripting your way to the top of the world.
As you explore the dystopian world of the future you meet new people and find new networks to infiltrate and compromise—or factions to ally with. You can also pick up new cyberpunk augmentations, boosting your body and your network to ever-higher levels, as well as develop your character's stats. There are also neat minigames, like stock trading, to uncover and master.
As you start to get deeper into the game, there's a nice big GitHub repository of markdown to help you out. Once you've done well and beaten it once, there is, of course, a way to get incrementing bonuses for future runs. The community is quite welcoming, too, if you get stuck.
