I figure now is as good of a time as ever for a quick plug.
If you do not own Shovel Knight, do yourself a favor and get it.
The game is among my favorite titles in recent history, and has some of the greatest music I've heard in the 8-bit style. Composer Jake Kaufman's also behind soundtracks for the Shantae series, and the DuckTales Remastered arrangements. The game itself is a love letter to NES games, bringing back memories of Mega Man, Castlevania, Zelda II, DuckTales and even a bit of Metroid. It takes the best of those games, brings them together with godlike music, and amps up the challenge.
It's on Wii U, 3DS, Xbox One, PS4, whatever console you have. It's coming out with a physical release soon. Free expansions with new stories and levels designed around different characters.
It may be a new franchise, but it's earned it's place as a famous indie game. Just do it.
