Add me to the vehemently opposed list. For me, the game is about “character development”—exploring the world, interacting with it, and experiencing it all with a fresh sense of discovery (which is necessarily diluted with each replay, no matter how well I’m able to turn off the “player knowledge”). To me, the “character advancement” paradigm, which I think is represented by the replay option, cheapens that experience for everybody at the table. After playing a number of LFR mods with one or more replayers, I’ve come to the opinion that, if anybody at a table has played a scenario before, it reduces the level of complete-party interaction—with replayers trying not to influence first-timers’ decisions—that can be such a big part of the fun (of course, if everybody has played it before, it can devolve into a completely different type of fun, but that’s another topic).
While I agree that sometimes there is a need to “replay without credit” to allow others a chance to play, I think this is best left as an unspoken, unofficial last-resort option.
