I've done a quick search on the forums for all threads mentioning Digestive Expansion dating back to 2007 and I couldn't find any threads that address this, so I'll throw this out to the DS community at large. Have there been any official or unofficial rulings from the game devs on how the digestive expansion bioware or the Vegsin transgenic alteration from Augmentation work with the advanced lifestyle rules from Runner's Companion? According to the RAW for their respective entries, Digestive Expansion provides a flat 20% reduction in lifestyle costs, and Vegsin produces a flat 10% reduction. Does that still apply if you use the advanced lifestyle rules to build a lifestyle? My GM and I took a look at it, and didn't think that I should apply the flat discount to the final figure for the lifestyle costs, and couldn't figure out an elegant way to make it work, since the necessities category of the advanced lifestyles is a relatively small part of the pie. His answer was to stick to the basic lifestyle rules to make life easier for all of us. That's what I'm going to do for the character I'm working on, but now I'm curious about how this should be handled.
