I'd have to go with WoW because I wouldn't take the time to enjoy cake as I do WoW. Not only that but I'm not big on cake, it makes you fat. And anyone that eats cake usually doesn't take it moderations like you SHOULD do with WoW. :shock:

EDIT: Or you can be like my guildmate & have both! http://img.photobucket.com/albums/v319/Tighfield/Misc/moe-cake.jpg
