Samus Returns. Always wanted to play a new sidescroller Metroid, and while it isn't really new, people tend to forget about Metroid II because it was on Game Boy. Still waiting on Metroid 5 and Prime 4.
It took me 2 hours to complete (1:25 in game time). I'm sure a seasoned player can beat it much faster. The camera controls take a moment to get used to. The game is very fun. I especially enjoyed some of the boss battles later on.
