Rotom having the Legendary theme in DPP. I wonder if it’ll keep it in BDSP? Hope so.
The opposite happens for Cresselia and Shaymin, they get the regular wild Pokémon battle theme despite being legendary/mythical.
Regarding Rotom, I also wonder if it was meant to be legendary at some point in development. I remember back from the early D/P days (when they were first released in Japan), it seemed to be unclear whether Rotom was a legendary or not. Personally, I remember that I thought that Rotom was a legendary at first because of the way it appeared, and how elusive it was.
Let's continue with saying more nice things about D/P/P! I have recently been replaying these games as part of my current project, and I have come up with some more things that I really like about them.
First of all, I like how Fullmoon and Newmoon Island are the complete opposites of each other in so many ways. It makes sense because they are the homes of Cresselia and Darkrai, which in turn are opposites of each other. Fullmoon Island is a lush, green area with a very nice atmosphere, being there has always given me a very positive feeling. It also has calm and relaxing music, which is neat. In comparison, Newmoon Island is partly deserted, with rocks and a mostly dry landscape. It has creepy and haunting music, and the atmosphere is quite scary. They are also complete mirrors of each other in terms of raw layout. One other interesting thing is the shapes of the small ponds located at the inside area of each island. The pond at Fullmoon Island is shaped like a Crescent. While this may just be a reference to Cresselia, it is quite similar to a new moon. In comparison, the pond at Newmoon island is more shaped like a round sphere, similar to a full moon. I'm not sure if the pond shape being contrary to the island name was intentional, but that's the impression I get from it, and I think it is really cool.
I also want to say that I really appreciate all the improvements Platinum did to D/P. Not just major things like the regional dex expansion, Battle Frontier and the Battleground, but the small details as well. I really like the graphical improvements Platinum did to Sinnoh, the region looks so much better, it is way more colorful and lively compared to in D/P. I also apprecaite the minor graphical improvements in the battle menus, item menus and even for the small panel which shows up when you enter a new area! I'd say Platinum is the best 4th Gen game graphically, that's for sure. I also think it is the best 4th Gen game overall.
One other thing I really like is how Platinum is so much faster than D/P. I have mostly been playing D/P for the past month, and while they felt very slow at first, I got used to that slowness after a while, to the point that it didn't bother me anymore. Today, I switched to Platinum, and it was so much faster that I got shocked! Going directly from D/P to Platinum gives a very noticeable difference in gameplay speed, especially in battles. But it happens outside of battles as well, the game just feels faster somehow. Although there are some things that are just plain better, such as the improved surfing speed or the fact that you can use the bike when going through gates. So I really like how they made Platinum faster than D/P.
Lastly, something unrelated to the Sinnoh games. Random and minor, but I like how in G/S, Unown-W had a different design compared to in later games.
Left is G/S, right is Crystal (and subsequent games). While I like its new design better, I think it is still pretty cool how it had a different design at first. This was something I never noticed in the past since I never bothered that much with catching Unown back in G/S (or Crystal), I learned about it from Bulbapedia in more recent times.
Edit: Fixed the images, they should work properly now.
