Well, last time I pick up an unfinished game and force myself to complete it. That was a pain.
But from hearing other people opinions - they found it fun and addicting. I find it utterly irritating. I hate it so very much.
Yes, there are other games like this. Yes there are about 4 other games like this with the same title - that I realized only when I pressed the submit button and was asked to change the title (!'s do add a lot).
