So what were your reasons for Digimon should be DLC, given that I wasn't here.
I will copy a text i posted already becouse i have to go eat now, sorry:
Tamagotchi AND Digimon are like brothers , bot are Bandai creations, bot are Virtual Pets.
Agumon was the mascot, together with Tyranomon, at the very first Digimon Tamagotchi in 1997.
And this was the first thing ever released for Digimon ever.
So yes , Agumon is a video game character as much as Game & Watch and all others.
The Anime was not the first , nor the second thing for Digimon.
Digimon games for PSX and Saturn were released before the Anime as well.
In Japan Digimon was NEVER a Anime thing.
The anime "completed" the franchise.
Digimon in Japan is a Virtual pet franchise, and aways was.
And in Japan Digimon is Big until today, with 2 new Digimon Tamagotchis to be released in 2019.
Alot of very good Digimon Games on the PS4.
And Digimon Survive on the Switch in 2019 as well.
Not even counting 2 Digimon games for 3DS that launched recently in Japan.
And just to make it a little bigger for you.
Sakurai created a Tamagotchi in 2005, inspired by Bandai Digimon Tamagotchi.
