"Your son", eh? Admit it, we're not here to judge

Well, Swiss Cheeseman is, and so is bringoutthegimp, but the other are not

(That's a joke, if you can't tell)
Which game is the best... well, it depends on what kind of game you like. Astonishia Story R ist supposed to be a good game, but nobody can really play it because it's Korean....
Little Wizard is a mediocre fighting game. Not bad, but mediocre.
Dungeon and Guarder is a good game I think. However, there are not too many attacks possible.... I like it, others don't.
Deadline: All for Princess/Her Knights is a mighty fine game and has a lot of possibilities, but can seem a bit slow. I think there's a Demo floating around somewhere, try it out.
