Playing to a future wincon

[Zachrulez]

I avoid alignment changing games. But I do think it's cheating to not play to your current win condition.

I don't see how it can be cheating to anticipate a change in your wincon. This thread of thought brings up a good question though in terms of what's more important. Is it more important to win the game or more important to play to your current wincon? Playing to one may not necessarily advance your cause to the other.
