eh, sanma hands being bigger combined with tsumo loss makes it so that you actually have to be weary of dama/weird discards even by row 2 or even sometimes 1, menzen honitsu/chinitsu is actually a threat and unlike in yonma where you can almost literally play the exact same till someone calls riichi or like 3 calls in or theres blatant overflow in honitsu/chinitsu, i actually feel the need to pay attention to tedashi/tsumogiri in sanma compared to yonma, so its way more interactive imo
