Rogue Flight is crazy good for what it is (on-rails spectacle shooter like Space Harrier or Afterburner.) It should be a no-brainer for this price.

Kamikaze Lassplanes, what a title!

the harvest moons are usually like $25 each on steam with their discount so pretty good deal on those

rabi-ribi is worth $10 alone, so there's more than enough to make this bundle worth it.
