I only dabbled with the Sims 1, but have played a fair bit on the second one, and actually I really enjoyed it. It's a well crafted game, if a bit too easy. But once you've 'won' it a couple of times with stunningly attactive people, you can turn your attention to creating virtual losers and tormenting them with your capricious Exodus-inspired whims. I dunno, it's fun. Also I liked that I could seduce the single mother and then refuse to let her kids move in with us. Enjoy your childhood suckers.
I think I like the Sims 2 better than Spore in the long run: Spore lost it for me after a weekend, but did give me a few moments of grinning like an idiot joy in the process.
Neither are as fun as Sins mind, nor as fun as Demigod is shaping up to be. Congrats Stardock, and thanks again for consistently making games in genres that I love.
