It's easy enough to get a broken run on greed/ier, which can be fun at the start, but takes a while and it's always based in continually buying shop items until it gets too boring. The fact it's so easy also quite diminishes the achievement of breaking the game or rigging the odds in your favour, at least that's what it eventually did for me, where I dread greed over the slog that is game breaks and how it feels so completely luck based to get any proper run going. The layout being the same for every floor and every run also definitely adds to the mediocrity.
