When I play a roguelike deckbuilder, the question I always ask myself is "would I rather just play Slay the Spire?". Usually the answer after a couple runs is yes, but Cobalt Core is a rare exception. It helps that it's clearly not a forever game, instead more of a Hades, where it is a straightforward story with an ending in the guise of a roguelike. It helps even more that it's extremely capable as a deckbuilder, using a lot of the fundamentals of StS but twisting it with a positioning system that actually works for once in this genre, and some really unique ways to switch up your runs. And then it's wrapped in the same charming character design, legitimately funny writing, and banger OST as its predecessor Sunshine Heavy Industries. Between that and this, I'm a forever fan of Rocket Rat, and will check out anything new they put out sight-unseen.
