My Sweetie loves to take games with an implicit premise and make the mechanics a sensible part of the game world fiction…. Think Order of the Stick and Erfworld, as campaigns, though with a lot less of the meta awareness and fourth wall breaking. So his D&D can have a very different feel from say RPGA’s flavor, or from the D&D run by a more story game oriented friend of ours. (All fun, but with very different emphasis.) People seem to gravitate to games that are rich in tools that they don’t enjoy building but still enjoy using, and it’s okay by them if that game lacks system support for the parts they enjoy building, because half the time they scrap those parts and build fresh anyhow.
