I know, right?
If you want to make an actual argument and put forth your reasoning for why he can't be considered a video game character in spite of spending quite a bit more time on the medium, feel free. Because your entire argument so far as been so blatantly "nuh uh" that I'm contemplating that report button. If you want to make a point, make it instead of repeating a non-argument.
There is no Goku argument - I'm being silly. Repeating the same thing over and over again and people like you not getting it is the butt of the joke. It's not meant to be taken seriously. It's a silly OT. Dragonball is a franchise which was adapted into video games, but its origins lie in manga so I don't think it belongs in a franchise celebrating video games and specifically its individuality from other media.
The butt of the joke is people who repeat themselves over and over in the face of overwhelming evidence to the contrary. And before you get confused again: that's you, and no amount of trollish antics like attempting to hide messages inside of posts will change that.
Being in one medium first over another does not automatically disqualify you from being associated with other mediums by your own logic. Goku appeared in a manga first, and like you said, has also appeared in anime and is considered an anime character. But the anime is an adaption of the manga, making your comments contradictory.
So which is it? Is Goku ONLY a manga character? Or is he manga and anime, but explicitly not video games? And under what pretense would he be disqualified as a video game character but not as an anime character? Because last I checked, Goku's video game debut was the same year as his anime debut.
