This is kinda sad but I have Pearl (my first Gen4) with over 400 hours on it, 5 boxes full of random pokes, a full legend box spilling into a second and all of my three ev'd pokes, (lol) Diamond which I actually got solely to restart on to get tms like Stealth Rock and if I felt like going through the game again, and Platinum which I never really got started properly on.
I think I might sell Diamond and use Platinum as a restart game and get a quick and easy team to raise but I'm not sure... (I have Torterra, Magmortar, Espeon, Rotom-W, Crobat and Weavile)
Do you still get the event items? Like the key to access Rotom's formes?
