The one I never get tired of replaying is Mafia 2. Maybe a weird choice since it’s very linear and every play through is pretty much the same. But the story is just perfect for me. The gameplay perfectly suits the story, nothing especially clever, just well executed.

Then there’s games like Binding of Isaac or Dead Cells where every play through is different.

Yup, ferrum is the Latin word.

Yeah, every word is made up. Looks like this one is made up “from lonia, the ancient region (western Asia Minor) occupied by the lonian people” as it says in the graphic as well as the suffix “stan”, which you probably know from some other countries and “is Persian and Urdu for “place of” or “where one stands”” according to dictionary.com.
