The stories are totally different. Platinum has Team Galactic wanting to take over the universe. OG Pokemon has Team Rocket that simply wants the strongest Pokemon. And... oh... yeah. I guess the stories are the same. lol
Nah. The story in the games is pretty bleh and repetitive, but I play it for the sake of becoming the best. There are like... 450+ Pokemon now. That's a lot of catching and raising to do. Then, of course, there's building strong teams, breeding for the best stats, etc.
I'm a bit OCD in my gaming. I love grinding. Maxing stats. Etc. The fact that the game is competitive in addition to this makes it even better. I love Pokemon. A great deal. It's not for everyone, but it is waaaaay deeper than its cutesy appearance would lead you to believe.
It'd be cool to play sometime, Logos.
For reference, if anyone wants it, my Pokemon friend codes:
