I am somewhat OCD (not horribly, in a can't function way... but for example, I took all my d6's and put them in a box, all facing the same way, I have about forty of them, they are stacked nine by four... this took time, and I have to put them back that way everytime I use them).
So for me, this just plain wouldn't work, leaving it incomplete like that would just nag at me and nag at me until I finished it.
