Pokemon Picross is a fun and interesting way of playing Picross, but I can see how some elements might turn a player off to the game.  If you opt to not spend any money, the experience can get rather boring as you can only do so much at a time before you have to wait a while to continue.  Still, the fact that you can get close to a third of the way through the game at no cost makes it worth at least checking it out, but I feel that things could have been done better.
