Haha that must have been fun I kind of make up my own little adventures too but I don't have a younger brother or sister my brother is 17 and I'm 14 but he's going into the military this Summer (I'm not in Sweden now I'm in America) So I can only laugh a lot when my cousins come over and I make up quests for them to do. You know sometimes I just feel like adding something into each Zelda game I found a typo in WW sometime but I have to play through to find out what it is. At the moment I'm fighting the Helmaroc King after making a new game about 4 hours ago. I have to say its my favorite boss.
And I like the idea of that such as like those Mario and Sonic Olympics? Am I right? Except like a little bonus games for completing something or doing a side quest I agree that they should do that.
I also need to say that the final boss of Spirit Tracks is easy, well at least to me I think I make it look easy to other people.
