Should I buy pokemon diamond/pearl or platinum?

Platinum is definitely better it's basically the same as diamond and pearl but the story is more fleshed out and a few other minor changes (like I think a few of the gym layouts are different).

Diamond and Pearl are the basics and Platinum is the advanced version which combines the two storylines from Diamond and Pearl. All three are great but Platinum is the best^^.

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.
