Not much of a post, just thinking about the SIZE statistic. I always liked it because it fit with the grittiness of RuneQuest but I don't think I ever used it (beyond how it gets baked into skills).
RQ 2 had size that was based on both height and weight. RQ 3 and Ringworld were based on mass. I don't know about Call of Cthulhu (Also It's kind of cool that spelling correction software knows how to spell Cthulhu). Below is the table from RuneQuest Classic (which is RuneQuest 2 with added bits).
