Favorite Game of All Time?

Since I haven't been posting much, I think I'll fill you guys in on what my favorite game of all time is. That is that I have played. Well, that was what I was going to do, and then I realized that I don't know my favorite game of all time. So, I though hard today about what my top 4 would be and I have them all. Tomorrow, look forward to me deciding which is the best of the best. What are the top 4?

Paper Mario: The Thousand Year Door

Luigi's Mansion

Halo 3
