Get off your high horse, they couldn't care less if you don't buy it, and do you honestly think they would attribute it to the online problems? They'd just do what they do with all the other sales, and assume either you didn't want it in the first place, or you got hold of it illegally. Refusing to buy the game because of some teething problems is at best childish, and if everybody actually did it, publishers would just decide that games with online content weren't as good at selling, and revert back to the old way of doing things.
Spore is genuinely enjoyable, I assume moreso if you're warlike and annhilate everyone else, however the galactic empire stage is particularly enjoyable. While the other stages are really mini-games, it's still the most unadulterated fun I've had with a single-player game in a long time (maybe matched closest recently by CoD 4). Whether it's been toned down or not, it IS a lot of fun, and it IS still a very innovative idea. When I get bored of the space stage (as I'm assuming I will at some point) I'll go back through and try and get to it using diplomacy. The point of the evolution stages is that you evolve to meet specific things, and during those stages they do make a difference, but once you get to the civ stage (as with humans) those evolutionary traits are largely unimportant, and it's the culture you're building that takes over. While the games are in short bursts and relatively easy, it's the short bursts and the fact that you have a viable target at each step, and that you are looking forward to the next stage that makes the game exciting and fun. As an FPS junky I wasn't sure I'd enjoy it, but after reading the reviews on meta-critic (including the linked press reviews) I decided it was worth the cash and stumped up. For what I've got for my cash, it doesn't seem quite as expensive as I first thought.
Once you get to the galactic stage and start terraforming, allying, fighting and trading, it's a whole new game and well worth playing through the early stages to get to.
