Here we have more proof that Sega's marketing was... well, odd.
Of particular note: at 17:04, they show the unreleased "Hammer vs. Evil D. in Soulfire", which is an M.C. Hammer game in which he seems to be throwing fireballs and dancing... which I guess must have been how Hammer spent his weekends. Please Hammer, don't hurt 'em.
Man, if someone could dump me a prototype of this game, I would love you forever.
