Wii Sports and Resort, Punch Out!, NSMB Wii, Donkey Kong Country Returns, Fifa games. But it's unfair to pick just a few. Every single game I stick with is because it's fun, simple and clean.

I love anything Contra or Hardcorps (except for that 3D Contra on PS2. Simply horrific). Right now I'm playing Hardcorps Uprising  almost weekly despite finishing it multiple times already.

However, Contra: Shattered Soldier is without question the most fun I had in the Contra series. This PS2 classic was fantastic and great fun. I would play it daily back in 05. I eventually became capable of finising it without taking a single hit. Not because I'm some hardcore perfectionist gamer, but because I became so familiar with the game and memorized all obstacles, threats, and strategies. God I love that game. I still pop it in every now and then.
