Lego Potter is a rental for sure, although I would probably go with the XBox version. Multiplatform Wii games are almost always worse than their counterparts. I do like the variety in the GH DLC, and I also like Mario Tennis being on the VC.

You can get the pet now, if you haven't already. I just got mine a couple hours ago, so I don't have any "game fuel" to put in it yet. I'm also the only person I've seen in Dalaran on my server to have it.
