Yes, in most tk games (DustBall, 4th Dimension) hero plays one of the main roles, heh...
I llllllove spoilerz. B)
In none of my games I ever made I played role of the God... Altrough I've usually put a secret location with me, like in TWoA - don't ask me about this game, it is rather my mind flooding rpgcode rather than game with storyline, heh - there was a city with great statue of Game Designer, blocking a house. After answering some funny questions to the statue you could pass under it's legs to the house, with Game Designer - the "Xanadu". When you gone out, it appeared you were at the moon, and going anywhere you ended up with house having item to return to the city...
In the nameless game I used to talk about, I'll propably have to do something more about gods, as they are virtually pawns of the main players: Archon, Char and the System itself.
Hero? Sure, he's your clone after all in one of the games...
