Whenever I'm in a Pet store, I always pass the Hindu/Buddhist statues in the aquarium section... some of which are superbly painted and dirt cheap. I'm reminded of the Ind Campaign I spit-balled on the Ol' SG forum, which amounted to nothing, really- a lack of official fluff, and too little research on my part (aside from watching Temple of Doom, I know little of the area...)
-When the idea struck me- what if, rather than a full on setting- what if there was an Ind side-expansion of Border Town burning?
For example, after I created Sartosa, Von Kurst merged it with the Lustria rules to make a setting for the islands in the New World (I like to call them the "West Inds".) I see no reason why BtB plus Jungle rules might not make an effective variant for an Ind (or a similar Southern locale, like Thailand (Tialan) , Vietnam (Siewkang), Tibet (Kitsevara), and Korea
(Han Kuo).)
In Ind, you might have
-Less Maruader influence- you might have the Hung, but others are less common
-Arab Influence - much of the country is ruled by the Arabyan influenced nobles, such as the Raj. Arabyan Tomb Raiders and Arabyan Warriors (Relics) would fit in.
-Cat-men - legends tell of cat-shaped beastmen in the jungles... who prey not on man, but live separately. They would use the same rules as Beastmen, but has the option of being a "Neutral" warband. (If so, may not take mutations).
Sadly, I don't know BTB well enough to do it myself... plus I have too many other projects on my lap... but I thought I'd spit it out there.
