For me, it's going to have to be Super Mario Sunshine: I've had so many childhood memories with this game (me and my sister literally used to take turns playing, and we both got emotional at the ending), and in my opinion it's one game that just never gets old for me! I can't remember the amount of times I've restarted the game just to experience the thrill of Mario cleaning up Delfino Island, defeating Bowser Jr., and then finally Bowser to save Princess Peach! There are so many great characters too, and I think Nintendo took a really creative choice by adding "FLUDD" to the game; although FLUDD is the water-gun that Mario uses to clean up the island, he ends up being Mario's sole companion by the end! Oh and if you have Action Replay, your really going to enjoy this game because there are so many glitches and cheats that you can add in to make the game more fun (Hint, I recommend enabling the Moonwalk MOD, it'll make Mario's air jumps last longer!) Anyways, just wanted to know: What is one game that your addicted to?
