I don't always agree with Gygax, this being one such place. If realism is the refuge of the scoundrel then a scoundrel I will be.And also:
"Interestingly, most of the variant systems which purport to “improve” the game are presented under the banner of realism. I have personally come to suspect that this banner is the refuge of scoundrels; whether the last or first refuge is immaterial. “Realism” has become a bugaboo in the hobby, and all too many of the publishers — TSR included — make offerings to this god too frequently."
"D&D is a make-believe game. It is designed, however, to facilitate close personal involvement in all aspects of play; this makes suspension of disbelief easier for those who can initially accept a game form which does not relate to any reality except a few tenuous areas... It is a game for the imaginative and fanciful, and perhaps for those who dream of adventure and derring-do in a world all too mundane. As a game must first and foremost be fun, it needs no claim to “realism” to justify its existence." -E.G.Gygax
