Everything about Hollow Knight taps my buttons in all the right ways: a dark setting (collapsing empire, spreading plague) with lines of hope (you, mostly, but a lot of the characters just want to live normal lives and are rather upbeat about their world) and some genuinely funny moments (Zote), an ever-expanding map with a great in-game explanation for both the layout of the world and the method by which you map it, and mechanics that just keep getting deeper and more interesting as you progress. It's just fun as Hell, and definitely worth the cost at the door. Plus the patches have been adding all kinds of useful stuff that aren't necessary, but make things better, not just bug-fixes (which there have been none, during my play). Only complaint? It doesn't seem to support my Hori Fighting Commander, which is my preferred controller for 2D games. Xbox 360 controller support is spot-on, though.
That maybe, just like how The Fans are a not-so-subtle critique on the people who clamored for more Hotline Miami and guys like The Reporter are comments on people who wanted non-violent levels, the 'bugs' and 'changes' are, you know, more comments and critiques on the fan-base and the genre? I mean, I didn't have a problem with this game and I didn't even finish the first one for being just too damn hard. Considering the patches so far have been for stability and real bugs, you'd think that if the things already mentioned weren't meant to be there they'd be gone by now.
