Nearly everything is a derivative of something from before. Occasionally something new comes up though. I don’t remember anything like Getting Over It seems to have created the Foddian game genre for example. And while Balatro uses relatively normal cards for its base, the gameplay itself is unique.









CPM is nearly useless because it doesn’t tell you what type of radiation… But for couple generic references, background radiation is usually about 60 cpm, and an international flight can be about 800 cpm.
So again, cpm is a useless metric without other context. It’s just the raw number of “hits” on the detector from any source it detects. Some particles are basically harmless, others not so much.
