If you collect video games, which game in your collection is the most valuable? This can be money wise or sentimental too. The game worth the most in my collection is my complete in box copy of Knuckles' Chaotix on the Sega 32X. My wife bought me this back in 2010 when it was only $40, now it goes for well over $400. I will never sell it though! As for the game that is the most valuable to me sentimental wise is my copy of Mega Man Legends for the PS1. My late grandmother got me this game at the age of 10. I even filled out one of those survey cards in the manual, but I never sent it off so I still have it. I tried trading it in at a local game store when I was a kid, but thankfully they didn't take the game. I would have regretted getting rid of it!
