I saw the mention of Hollow Knight in the L&R thread and liked the art style so picked it up before that episode aired and the Don't Skip was made. Man I loved that game. For as much as EZA goes on about Shovel Knight being the best platformer around I really, really like Hollow Knight more. It really felt more Metroidvania whereas Shovel Knight was a lot more Mega Man.
I've heard a lot of people complain that it's too slow. And while true the first few hours you are pretty limited in powers and map traversal that all changes as the game continues. I also enjoy the more methodical pace where you can actually appreciate the backgrounds, mobs and soundtrack. Monster design is top notch with cool modifications to standard enemy tropes.
In all honesty, Hollow Knight is pretty much my GOTY at this point.
