I only know German Dub and like Palmon's voice there. ^^ But I sure can look into the japanese one just to see what it is like. I mean, your description makes it sound extremely alluring. =D Funnily enough I wanted to do a Palmon Trainer game first, but it proved too ambitious for a first game, so Gomamon Trainer was the alternative. Still have the old Palmon Trainer prototype I plan to build up upon after Gomamon Trainer is done. Found a good place in the Digimon Adventure story too, even though it is more of an Alternate Universe thing there, instead of something that seamlessly fits in like in Gomamon Trainer.
As for the series, I liked it up until Season 4. Season 4 was a fun world to explore but sadly no partner Digimon which is a weakness, though I had tons of fun with it regardless. =3
Season 5 with Data Squad was actually the first Digimon show I disliked. xD I didn't like the bland less colorful look of it and the designs and story seemed more bland and boring to me. Sadly Season 6 is a mess. Watched half of the first season as only that much is dubbed, but it is such a cliche show with the bad guys going "Oh! I am evil! Look at me doing evil things!" that it is hard to take serious. The fact that they are ignoring the level system is the worse offender though.
Digimon Ghost Game, while not perfect, is actually one of the better Digimon shows. It doesn't move forward enough for my taste and is mostly self contained episodes, but I hope it will progress more soon. It is good enough at least that I enjoy it every Sunday together with my brother. A fun time. ^^ Kinda have the hots for Gammamon and Jellymon-sama too, but hate that fat rabbit. xD
Anyway, I am glad you appreciate this idea I used for the story. It was a perfect place to fit with the portal to the human world and those cards. They were a pain in the ass to draw though as there were so many Digimon I had to draw for the art. xD Though I think it was worth the effort. ^^ You are doing well in English I believe. Keep doing your best. I will try to do as well! =D
