Most of you put me to shame! Not just in backlog, but in sheer number of Wii games owned. And Lindemann, I bow to your backlog greatness. You are the Master, no the Potentate!, of gaming backlog. I feel ashamed to even be in your presence... on a blog.
Anyway, my offering is meager, but here it is:
1. Cave Story (presently playing)
2. Guitar Hero: Van Halen
3. Prince of Persia: The Two Thrones (GC)
4. Lego Harry Potter: Years 1-4
5. Epic Mickey
6. Marvel Ultimate Alliance
I just finished Hulk: UD, Xenoblade, and Sin/Punishment 2.
There are others that could be on this list, but it's more like completing the extras than beating them. I'd like to collect all the coins in NSMBWii, defend my title in Punch-out!, complete hero mode in Skyward Sword, etc. Not sure any of that's going to happen, though. Not enough time.
