Exactly.I'm guessing that the flag means you just finished that stage but the rainbow crown means you've found all the hidden stuff etc?
On my normal run, I only missed the things I didn't find, but in some places it is very possible and easy to miss things the first time through. One of the levels with Falcon/DK/Diddy/Olimar comes to mind, with Falcon being the only person that can easily reach a certain area.You should be able to complete it all on the max difficulty without having to redo it all.
Also most of the things from it are not very important. Ofcourse I will get eveything later but for now I got all stages and characters.
Adding someone like master chief on the other hand would be different.
Not true, microsoft no longer owns master chief, but the company that does is still highly loyal to microsoft Xbox 360 and XP / vista. A while ago the company split from microsoft if I remember to form its own company but still continues making games for the 360.And Master Chief is very much exclusive to Xbox, X360 and Windows, so I doubt Microsoft wants their character in a game exclusive to another console. Obviously.
whered u hear that?
