EA should be ashamed of themself for the draconian DRM/Copy protection method they have employed for Spore. Be warned that you can only install this game 3 times and should you upgrade your hardware or EA's validation servers fail/be taken offline your copy will become entirely useless. It's my one major complaint about Spore and it's a significant problem.
DRM issues aside it's a lighthearted game with seemingly infinite creative possibilities. I'd highly recommend it to children and adults alike, although it won't appease the 'hardcore' gamer crowd with it's relatively shallow gameplay mechanics. The majority of the content can be found creating creatures, buildings and technology or exploring that of other players actively sharing their creations.
However my review score stands, EA should address this SecuROM issue immediately. Had I of known before my purchase I would of boycotted the product for it's inclusion alone, very unhappy about it indeed.
