I agree to this, i quit supermechs a couple weeks back because i made some pretty big mistakes, id love to restart.

I agree. I also stopped playing SM as because of errors I made in the past, there was no good option to continue and the game ending in grinding. Therefore it became boring and I quit.

I am sure a restart option would help to keep players in the game, as the learning curve is quit high (due to the resale values).
