You do get what the concept "Console exclusive" means?! The titles you have named are contracted to be exclusive to Microsoft, and Microsoft machines ONLY. There are no legitimate ports, only illegal hacked versions which are only playable on hacked consoles.
Where to get them? I'm sorry. I don't support piracy.
I would get the new black Xbox 360 if you don't have it but if you want free live then get the PS3.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
