As pretty much a few of the sane fans left, the franchise's biggest asset was its music and most of its music aside from Lost World were mostly butchered vocal tracks with 2/3's of their songs still missing, zero new remixes (I think like 3 of those DK songs were new remixes)
From how his moveset goes, look how much detail most third party characters (
) and compare them to Sonic where
where outside of his speed, his moveset is mostly made up from the ground up and it's detail is 2 moves being the goddamn same, Sonic Rocket from Battle (his down air) and his down throw from Sonic the Fighters and don't get me started on the alts (I don't care about Sega influence, atleast try with it)
I ain't saying Sakurai hates Sonic but it feels like he doesn't have that detail and feel just mesh together. DK has that detail and better stuff compared to Sonic.
