Silly games
I guess it's just a habit from being a kid. I love silly games. Cheap-ass games (tm) like "Give me the brain" are fun to just sit with friends and play. So when something like http://helixville.myminicity.com/ comes across my friends list, I usually have to give it a look. In this case, I think this could be fun. Get all your friends to click on the link to your town, and build it up to world domination. These sorts of games unfortunately tend to go the way of fashion, and not last long enough to really get serious play and game strategy, but we will see.
