As ever with these trends, copycats have started springing up.
No one is playing any of these games because they're 'fun' they're doing it for the skins. It would be kind of funny if what ends up killing the skin market overall would be these idle clicker games unless Valve decides to have a clamp down.
I'm still pondering the maths behind the trend a bit, with botting and cheating it's definitely going to be worth it for some people to do this. All I know is as far as I'm concerned multiplayer gaming that has any kind of micro-transactions like this are massively dead to me and these idle clickers are clearly an exploit people have found in the market.
Edit: There's a third copycat game that I didn't notice LOL, the cancer is spreading

If mainstream media is reporting on something like this without shitting on it, it's not important enough to worry about and is a distraction from things that are.
