I think it _could_ work, but it will almost always be mostly benefitting the developer, and not the game unfortunately.
The second part is a bit more tricky, as people don't want unnecessary responsibility.
There are games that could benefit from obligation, like god games.
Just think about it, if you where the god of a small village and raised the people on it from the moment of birth, feeding them, sheltering them even teaching them. If every thing you did for them took real time or money, could you sacrifice them for power?
I believe this is what Peter Molyneux thought too, but it is really hard to sell that idea... Probably would have been easier if he didn't do a kickstarter project out of it though...
thy [...] thy [...] thy [...] thy
But why do you hate the letter e?
(your usage of "thy" is very confusing. Obviously you mean "they" but "thy" is also an english word (though archaic) with a different meaning from "they", so I kind of stumble in my mind each time I come across it in your texts, since I have to re-map its meaning...)
