No. The game, overall, is different just because they've stuck editors into it, that don't serve much of a purpose anyway.
Had the different gameplay elements been actually embedded into eachother, we could have been talking about something original. When a game is basically just a series of already existing minigames stuck together, it's not original. Raving Rabbids averted that, because the games were original by themselves. WarioWare averted that, because partly the games were original, and partly because it all relied on a slightly different set of skills. Spore takes no effort to somehow make itself original, except the aforementioned editors, that, as said, have virtually no meaning.
If we pick the game apart, we get Fl0w (with an editable creature instead of progressive evolution - which SHOULD have been in this game), a barely-scraping-by action/adventure (with the editor instead of, say, an inventory interface - I mean really, what purpose does it serve other than the usual "dress your doll" routine, that with the parts being all that matters?), an incapable invalid RTS that looks a lot like LotR:BfME (with editors, again, for the creature's outfit - nevermind that you barely ever see your creatures up close at this point), another incapable invalid RTS that looks like the previous one mated with Massive Assault (again with absolutely meaningless editors, since you neither see your creatures up close, nor do you usually care for how do your forces or buildings look, as long as they work), and the final bit of icing on the coffin, the "explore-the-galaxy-completely-alone-and-do-whatever-you-want" space phase, that is surpassed not only by many commercial games in terms of gameplay depth, but also by indie and freeware ones.
Really, I see nothing in this to pay for. I am glad I didn't. And I no longer own ANY copy of it. Until it gets completely redone, it's not worth the time and traffic to even download it. I won't even waste a .5$ disk or hard drive space on it.
Also, "it is not stealing when what you steal is rotten". I mean, seriously, there's a reason companies are paid to dispose of trash. Why should we pay for trash? If you need trash for some reason, even trash produced by a specific company that sells it - which already does not make much sense - you should be able to go ahead and take it for free. If it is useless and you see a use in it, you can choose to pay for it, but a useless thing is worthless by definition.
