There are roguelites that are fun but just too stressful to fully enjoy (Invisible Inc, Into the Breach) and those that somehow avoid being stressful (Slay the Spire, Hades, Dead Cells). Maybe it's fundamentally just difficulty, but in the stressful ones it feels like you have to play perfectly every single turn or an entire multi-hour run gets scrubbed. Haven't tried FTL or Binding of Isaac yet to see which category they fall into.
