1) I enjoy many aspects of campaign settings. When I make one or adopt one it can last for many years of game playing (across many adventures, many modules, multiple campaigns), therefore not a frequent purchase. In Roll20 I would like to buy elements that help me build-up / flesh-out / or add to the process of making my own campaign setting. And it would be offerings that would help save the purchaser time in terms of Roll20 set-up for a setting. It would be "plug-and-play" in the sense that purchaser could incorporate any 1 part of the setting without necessarily buying or adapting the entire setting. 2) I would not consider buying a "Complete" campaign setting in Roll20, it would just be too much information to swallow, it could be 100's of pages and 100's of maps at that point. I would consider buying flexible elements/ modular packs that could be folded into a custom setting of my own, or added to an existing campaign setting to modify it, or combined all together to make World Of Andrew setting; like the building-blocks of a campaign setting without being so specific that it becomes restrictive. I would consider buying: World map pack, includes globe, includes 3-7 continental maps, includes 5+ state/region/county maps from each continent, includes at least 1 city or village from each state/region. There could also be diagrams of the planes, or trade routes, or past wars front-lines in the setting's history. People Pack, detailing all the races/species of a fresh new campaign setting, but can be used as a modular drag-and-drop to add this collection of races to an existing game. For example this might contain Humans plus 5 new races (for example say maybe Frog-People, Minotaurs, Aliens, Talking Caterpillars, and Spirit Reavers), no mechanical rules that would limit to a certain game system, each race would have Description, illustration, background, backstory, homeland, sample city, sample house, many Tokens of males & females in different professions. Monster Pack. Here are 100 monsters unique to this setting and they are all new monsters that you never heard of from D&D games. Token and description for every monster is set up, if there are any stats it would be just enough to describe the strength/power level, nothing specific like exact damage amounts, hit points, or stats from any particular game system. Like the instruction "Just add water", the purchaser would just add stats for the purchaser's game system, keeping the token / appearance / description of the monster from the purchased Setting material. Adventure Pack, contains maps, locations, plot hooks, descriptions, threats, traps, characters to meet, for multiple adventures within a certain region of the setting. 3) I would have 5% or less tolerance for system specific. Probably wouldn't buy it if it was system specific whatsoever. The most specific that I would accept and still buy it is "This is a fantasy world (high fantasy or low fantasy?) with monsters and setting-flavor that could work with games like D&D or Basic Fantasy or PF or GURPS or anything".
