This. If implemented, this would be an inventory nightmare. First of all, how are these variances going to be listed? Mithkabob- Hold the Onion? Sub Sandwhich No Mayo + 1?One or two patches ago we finally came to the point where recipes for everything, including food, got easier, less complicated, less "You will have to carry around 300 different ingredients for one slice of pizza".
But now Rokien comes and thinks it is a good idea to make those recipes even WORSE than before with 34 different versions of every recipe..
Think carefully about this. Look up every food recipe and then multiply each one by the ingredients involved, and possible substitutions. Now add that total again for +1's. Then you have to come up with unique stats for each, and every one. There comes a point when adding overly complicated systems serves no genuine purpose beyond complicating things.
