From Dust is genre-redifining? How so? Not wanting to tell you which projects to back, but WFTO looks like a complete knock-off. Even Evil Genious was more original or had at least a different premise.
From Dust, in my opinion, most certainly is - as it sets the bar so high, that I suspect Molyneux will be unable to pass it. The abstract story was worked in wonderfully, and the limits to terrain manipulation were well balanced. Judging from the material put out thus far, I do not judge Godus to meet the (admittedly) high standards I have.
Having read a lot of the design documentation for WtfO, it is a 'knock off' only in style and premise - necessarily so, given the legal constraints. The gameplay itself is apparently significantly refined, adapted and inspired from DK, which is one of my favourite games of all time, with an exorbitant amount of modding power built into the framework - so as to let users tailor any/every aspect of the game, from adding new spells/monsters/traps, to inventing unique game modes. That is what a 'God game' *should* be. Plus, they have had a playable showcase since Day One - which has only today been upgraded into a full (albeit alpha state) demo, which actually provides a feel for the game.
Black & White enters my list of beloved titles, as well.
WtfO is a title shaping up to be extremely close - but superior - to that which I love, Godus quite simply (again, judging from the material available - which should be the impetus for any game development KickStarter) isn't. Hence the former having earned my money.
