Anyone had any luck converting their game into a template to sell on Chupamobile or similar sites?

If so, how profitable is it?

How difficult is it to run and maintain?

Is it a good source of income for indie game devs?

How does it sell in comparison to direct sales?

Is it a good idea to do work on your game and your template or is it better to just pick one and focus on that entirely?

If you make money through templates, what is your favorite site or service to sell on?
