Yes, mainly because there are many more opportunities to get rarer Pokemon that you couldn't get in Pokemon Pearl without cheating.
you can only get one mespirit in Pokemon diamond, pearl and platinum; unless u cheat.
In regards to PKMN Diamond and Pearl versions, there are two pkmn eggs obtainable as gifts. The first is that of a Happiny, obtained from the NPC Traveling Man in Hearthome City. The second is that of Riolu, obtained from the NPC Riley, after driving out the Glactic Grunts on Iron Island.
at least 10 ON THE SAME POKEMON
