Lost me on that comment about Planet Puzzle League. That version is ace...doing away with the extra character stuff for pure style.
I found Planet Puzzle League bland even though the gameplay was good due to the stylus controls. (What makes it worse is that I only play one stage in that game for Score Attack because I don't like the soundtrack.)
Magical Drop 3 and Panel de Pon are some of my favourite puzzle games and that aside from the gameplay, the characters and animations have appeal which is more interesting to look at.
That's why I have difficulty playing games like Tetris because it feels so dull in comparison.
