I've had Desktop Heroes running on a side monitor for the past week or so. It's a fun little Cookie Clicker–style game that I enjoy watching from time to time. It needs minimal interaction, and you level up characters and progress as you normally would in a small RPG. The "screen" for the game is the bottom 2/5ths of your chosen monitor and can go transparent if needed.

There are a few small currency systems in the game that can be used to purchase sustained effects and temporary ones for your adventurer and his colleagues. Some of these currencies, like the Magic Orbs, can take a while to attain over time, but there are also currencies like the base gold that you start to level up quickly—but you can tell that it moves to an exponential scale fairly quickly. The numeric system cracks me up as it goes from tens → hundreds → thousands … all the way up to quintillion, then starts into a letter system all its own.

After playing for about a week, I think all my characters are around level 200, and XP does seem to be scaling in the exponential range a good bit, so I figure the ramp-up from here may be brutal in the end. I can see about 1.5% of Steam players make it to level 500 for their entire party, so that's the goal. It's not like I really have to do anything.
