Minna no Oujisama is a horrible, brain-sucking game. And I adore it. I've already beaten Sekigaku's game (all shall fear my fast typing skills, yo) but the other two... Sei-Rudolph's is near impossible for me. I hate the puzzle slidy things. ><;; And the other one I'm doing on pure luck. I don't know what school it is though. The picking up balls to see if Ryoma's on the other side thing.
But, oh, I love Sekigaku's game. I almost lost against Eiji (because I was 'OMG, how does this work?!!11?' xD) and Momo because it was so fast. So much switching balls so fast...
I prefer puzzle games to the actual tennis game, because I have an idea of how to work it. xD Like on my CCS GB game, I'd just play Tetris because the time was messed up. >>; I never did capture a single card on that.

But, oh, how I like this. ^___^ I was playing it for half an hour and I've beaten the first stage. Ha. They never stood a chance.
