a huge part of this is that in game crit *feel* is absolutely essential to talking about the experience of playing a game but it's always, always, always easier to talk about the systems because that's a Thing/Not-Thing where feel is like "I dunno I like it when you smash stuff"
but that's also got me trying to figure out what the difference between the Metroid-centered search-action game and the Castlevania-centered one is. Is it just melee versus missile combat? Platforming intricacy? Narrative focus?
