Ryu in every other SF game: Distinctive old school playstyle shared by a small handful of other characters but also more solid in other areas giving him many options in many scenarios and a good character for noobs to learn with. Also usually has some cheap bullshit gimmick that lets him steal rounds from an 80% life deficit.

Ryu in SF6: Same 'low forward xx slime' playstyle as everyone else. Character uniqueness boils down to having 10% less throw pushback and 10% more combo damage than other characters. Also a vestigal projectile that's almost useless.
