Being a "conservative" gamer I still have an imagination
If the world cuisine style is "good" why then naturally the "other" must be representing the opposite side of the bell curve; bad. However the "other" isnt really defined to give a good comparison, after all a full page was dedicated to one side;the world cuisine side. While a mere paragraph if that for the other. You should in shorter summary, better define your thoughts, creating a clear distinction on the contrast of gaming styles, and respond. In short "YOU FAILED YOUR DIPLOMACY CK!!!"
Now in answer to what I believe your question is, yes. I have found that most DM's , players and whole gaming groups that I have met, mix it up a little. They try to liken their scenary to a euro castle and (silly English Kiniget) Knight flare with a arcane and/or divine base. While in these lands most customs will be the same.
In our group we play a "combo pack" "go big" "supersize me" style. After all variety is the spice of life. We play The Empire (simply known as the Empire) is dominating all they can, Roman esk' lawful evil govt, with a Nazi like no magic policy, unless your part of their clericy. Any other cleric, warlock, wizard, soceror, psion, anything with supernatural abilities will usually find them selves hunted down and thrown into the gladiator pits.
Outside of the repressive empire there is the Lawfull Good Kingdom of Albion (castle, knights, Palidons, Clerics, wizard euro setting), there is Hybernia a fey setting with a mix of Scottish warriors/barbarians and the insane blue picks or bezerker clans. Midguard with a Nordic/Viking setting...complements of a on line game caIled dark ages of camelot.
If you were to travel a bit, you would find a continent that represents LoTR with Halfling shires, plains horsemen and a CH Evil power hungry demon summoned by a wizard whom the demon now controls. He has mind controlled mages doing his bidding thruout these lands with Ork armies to boot! - A few fight with the Empire have recently happened....and another continent that represents the oriental adventures setting.
So there you have it, a dominately conservative gaming group with wide variety in there world......some tradition...some not....like a earlier reply most gamers are in the middle of the football!
