What’s funny is I own this game already and it’s in my top three yet the strategy is so deep I hadn’t even considered this until now! Now that you mention it though it is light and takes up little space, the actions are practically displayed on the tiles, and despite not having perfect information you’d have enough information to deduce what the best move would be while still having enough randomness that an inexperienced player has the ability to make a “comeback”. This game just keeps getting better lol
It is true! Someone much more studied on this than me could provide a better explanation, but instead of “size” it’s called cardinality. From what I understand your example of even integers versus all integers would still be the same size, since they can both be mapped to the natural numbers and are therefore countable, but something like real numbers would have a higher cardinality than integers, as real numbers are uncountable and infinite. I think you can have different cardinalities within uncountable infinities too, but that’s where my knowledge stops.
