Should I get pokemon platinum or pokemon heartgold?

Pokemon Platinum version has a few new things:

-A new character named "Looker" who's a detective after Team Galactic

-A new Team Galactic member

-Different Pokemon

-A Distortion World

-Girantina's Origin Forme

-Shaymin's Sky Forme

-New Gym Puzzles

-A Wi-fi Plaza

That's pretty much it. Other then that it's the same as Diamond and Pearl. I suggest getting HeartGold for a change of story. Plus, HeartGold has more features then Platinum, such as a Wi-fi Battle Tower, the new PokeWalker pedometer, and better graphics. Also, HeartGold has the Wi-fi Plaza of Platinum.

Get Platinum since you already beat the elite four and kanto gyms in HeartGold. And I feel your pain for losing HeartGold since I lost my Pokemon Pearl

Get heart gold. why? Well the annoying thing about diamond is taht it mixes all the pokemon from the 4 generations together. I perefer heart gold where all pokemon are generation 2 (and then generation 1 when you have access to kanto)

Play the originals. Red and Blue and Yellow. Then play Crystal.

Or just get platinum. l love my game and I have diamond.

Differences

Snow. much colder

New designs on charters

Barry is really wants to get the hell outta there

you see Cyrus much earlier in the game

new designs gym galactic headquarters

free porygon

togipi egg from Cynthia

new Pokemon in sinnoh

i just can't list em all ;)

Pokemon Gold. Not Heart Gold, but the original.

Heart Gold.

dont get platinum its almost the exact same as diamond or pearl, get soul silver then or a pokemon mystery dungeon

get pokemon heart gold its newer and better

well if you want to use your diamond to help yourself in platinum you could do that if you are sure about the two choices. it'll make it funner, trust me
