Hard to define obscureness since it also depends on regions, age, etc.
From last generation it would be Trauma Center: New Blood, We Cheer 1, Rhythm Heaven and Picross 3D.
From PC PangYa, GunBound or Ragnarok Online; then sim builders like Pharaoh, Oasis, Constructor, etc (then there's Theme Hospital but that's not obscure). I'm sure there are more PC, but these are the ones I remember right now.
