OK Mark, so this is how you want to play?
Fathers and sons in computer games.... And I guess the house-rules still counts? Or do we use father-figures here? If we do, there is Twinsen, fighting the evil tyrant Dr Funfrock, to save his world, Twinsun. In the end of LBA I the mother-figure rises and envelops Twinsen in her love when he has conquered the evil tyrannic father-figure...
This game is interesting because it is a game where the NPC's take on a compelling realism, some of them annoyed with Twinsen, some eager to help, some betraying him: he is not safe anywhere, but can have sudden and surprising allies. He fights oppression, and in LBA II he is himself the father figure, having detroned Funfrock his sweet-heart is expecting a child. Provoked and fighting for the future of his own child he fights to save the children of his world as they are abducted to an other world in the grasp of an other evil tyrant.
So in these games we have the evil father who has to be killed for the boy to become a man, the man metamorphosing into the good father, fighting to protect his offspring - as well as the society held down by an oppressor, quite reminiscent of East-Europe despite the fantastic flavour of the game, perhaps a Computer-game of the oppressed as Gonzalo is looking for? Typically it's produced by the once French company Adeline Software. Why typically? Because Little Big Adventure introduces the social conflict with more colours than black and white: Twinsen is the hero but he can't do it alone. He also doesn't appear to be a particularly strong hero, he's just a little clever, he talks to people, he figures things out and there's a lot of trial and error on both the player's and the character's behalf.
Did I like it? Oh yessssss!
