Heya!
Most of Wizard City is FREE, so I suggest you try that out first, you'll know within the first hour or so whether or not it's a game for you. If you do decide to try it out, make sure you post your wizard name on the Wizard 101 thread so you can possibly meet up with some other Disers. It is in no way a replacement for VMK, but I like it. I keep hoping they'll add some more features for building and community activities.
