Yes. My Non-Humans Are Rarely Any More Alien Than Could Be Played By Humans In Latex Masks. I Find Truly Alien Characters, Characters Who Think (In John Campbell's Felicitious Phrase) "As Well As A [hu]Man, But Not Like A [hu]Man") To Be Too Difficult To Sustain In A Long Adventure. Playing A Mostali [RuneQuest Dwarf) Made My Imagination Hurt, And I Simply Can't Imagine Playing A Dragonnewt Or RuneQuest Elf. So You Find A Few 'Elves' And 'Dwarves', 'Flyers' and 'Divers', Gathin, 'Naiads', Leshy, Giants, And Sprites In My Campaigns, But They Are All Essentially Humans With Makeup And Perhaps An Occasional Special Ability.
