Wow. This is surprisingly difficult. Like...there was player 2 in stuff like Smash TV maybe, and beat-em-ups with selectable black characters, but I don't really think that counts. Was it San Andreas?! It couldn't be San Andreas...could it?https://twitter.com/DannyTheElfGuy/status/1002233099835662337 …
Beverly Hills Cop (1990) technically counts. Street Fighter/Streets of Rage/Rival Schools/Mortal Kombat (beat 'em ups), Barrett in Final Fantasy VII, Blade on PS1, a couple of Michael Jordan games, Michael Jackson's Moonwalker (genesis), Shaq (Not counting sports games, btw)
