Nintendo 64: Kirby 64: the Crystal Shards, 1000 Wii Points

Kirby’s first 3D outing, and his only 3D adventure, hits the Virtual Console. Kirby 64 has you playing as Kirby, moving through two dimensions (movement is restricted to a 2D plane) as you travel across six worlds, collecting the 100 pieces of a crystal. In a first for a Kirby game (and perhaps another "only"), you will be able to combine the power of two different enemies to create an entirely new power, more powerful than the first. This game also includes three multiplayer minigames.

TurboGrafx-16: Psychosis, 600 Wii Points

Your soul is at stake in this interestingly-storied shooter for the TurboGrafx-16. Your soul has entered an evil realm, ruled by the demon Ugar, and you’re going to have to use your ship (???) to blast away at the enemies clogging your mind. This game consists of five stages, known as "causes", with a large boss at the end of each. As you play, you’ll upgrade your weapons and gain satellites; said satellites can help with your weaponry, or be repositioned to take enemy fire for you.

I’ve always wanted to try out Kirby 64; I guess now is as good a time as any. The power-combining aspect looks like fun.
