Three perspectives on how board games get made, from prolific publishers with different business models (video)

“Games are better if they hold up to competitive play, but they MUST hold up to non-competitive play. Don’t allow your game to drag on or fall apart if players don’t pursue victory as aggressively as you expected them to.”
— Seth Jaffee
“Don’t automatically conflate a game’s set-up variability with its replayability. After all, based on centuries of evidence, Go and Chess are the most replayable board games. Instead realize that a game’s replayability often results from the variability within its players.”
— W. Eric Martin
“Ideas are a dime a dozen & mean nothing if the work isn’t put in to actually make a game out of it.”
— Jason Dinger
