I'm still intrigued in Spore, and here's why.
I played SimCity, and I fucking loved it
I played SimCity 2000, and I fucking loved it even more
I played SimCity 3000 and 4, and they were great (not as good as 2000 but we won't get into that)
I played the original Sims with most of the expansion packs and they were fun games (although not that fun in the long run)
So, by doing the math, and realizing that I fucking love Will Wright ideas, I'm going to probably pick up Spore, because I will most likely enjoy it. But not right away.
The thing with Maxis games is that you play the fuck out of them for two weeks and then you pick them up later on whenever you get bored and interested in playing them again. I probably won't buy Spore right off the bat, but I will be buying it, rest assured.
